Abstract: The polarization of the lightwave at the input to a heterodyne receiver can be determined by measurements of the amplitude of electrical signals without the need for phase measurements. This allows more accurate measurements of the polarization in the presence of noise and allows a determination of the degree of polarization of the lightwave.

Abstract: A tunable optical cavity[200, 300] constructed from a fixed mirror[214] and a movable mirror. The fixed mirror[214] is attached to a substrate[203] having a first electrically conducting surface. A support member[216] having the moveable mirror[213] supported thereon and having a second electrically conducting surface, is suspended above the substrate[203]. A circuit[250] applies an electrical potential between the first and second electrically conducting surfaces thereby adjusting the distance between the fixed and movable mirrors. The fixed mirror[214] and the moveable mirror[213] are positioned such that the mirrors form the opposite ends of the optical cavity[200]. The distance between the fixed mirror[214] and the moveable mirror[213] is a function of the applied electrical potential. The fixed mirror[214] is mounted in a well in the substrate[203] such that distance between the support member[216] and the substrate[203] is less than half the distance between the mirrors.

Abstract: A tunable optical resonator[100] constructed from a fixed mirror[14] and a moveable mirror[13]. The fixed mirror[14] is attached to a substrate having a first electrically conducting surface. A support member[15-18] having the moveable mirror[13] supported thereon and a second electrically conducting surface is suspended above the substrate such that the moveable mirror[13] is separated from the fixed mirror[14]. A light output port[13] transmits a light signal of a wavelength determined by the distance between the fixed and moveable mirrors[13]. An optical circuit[102,104] measures the power level of the light signal and generates an electrical signal that depends on the measured power level. A frequency adjustment circuit[106,120], responsive to the electrical signal and a tuning voltage, applies an electrical potential between the first and second electrically conducting surfaces. The electrical potential causes the distance to remain at a distance determined by the tuning voltage independent of the power level for power levels less than a predetermined power level.

Abstract: A tunable optical cavity constructed from a fixed mirror[214] and a movable mirror. The fixed mirror[214] is attached to a substrate[203] having a first electrically conducting surface. A support member[216] having the moveable mirror[213] supported thereon and having a second electrically conducting surface, is suspended above the substrate[203]. A circuit applies an electrical potential between the first and second electrically conducting surfaces thereby adjusting the distance between the fixed and movable mirrors. The fixed mirror[214] and the moveable mirror[213] are positioned such that the mirrors form the opposite ends of the optical cavity. The distance between the fixed mirror[214] and the moveable mirror[213] is a function of the applied electrical potential. The thermally induced vibrations are reduced by utilizing an electrical feedback circuit that measures the distance between the mirrors. The feedback circuit dynamically changes the potential between the substrate[203] and the support member[216] so as to reduce fluctuations in the cavity resonance frequency. The instantaneous cavity resonance frequency can be measured by comparing the cavity resonance frequency with a standard optical signal, or by using a circuit for measuring capacitative coupling between the support member[216] and the substrate[203]. The feedback circuit varies the potential between the substrate[203] and the support member[216] so as to reduce the fluctuations in said measured cavity resonance frequency or the capacitance. The optical cavity of the present invention can be utilized in constructing a tunable laser by including an active layer[355] for amplifying light trapped in the cavity. In the case of a tunable laser, the thermally induced fluctuations can be reduced by including an interferometer[360] or other frequency-selective device to determine the instantaneous wavelength of the light from the laser. An electrical feedback circuit[375] varies the potential between the substrate[203] and the support member[216] so as to maintain the measured instantaneous wavelength at a specified value.

Abstract: A tunable optical resonator whose resonance frequency is determined by a light signal introduced into the resonator. The resonator includes an optical cavity[10, 306] having a first mirror[13] and a second mirror[14]. The first mirror[13] and second mirror[14] are supported relative to one another such that the distance between the first and second mirrors may be altered by applying a force to said second mirror[14] thereby altering the resonance frequency of said cavity. The resonator includes a light input port[13] for receiving a tuning light signal, and a light signal generator for generating the tuning light source[302]. The tuning light signal is introduced into the optical cavity[10,306] such that the tuning light signal is reflected between the first and second mirrors. In the absence of the tuning light signal, the resonator has a resonance characterized by a resonance response curve centered at λ 0 . The tuning light signal has a wavelength λ 1 within said resonance response curve and sufficient power to cause said resonance response curve to shift such that the resonance response curve is now centered at λ 2 , where λ 2 >λ 1 . In one embodiment of the invention, a circuit[403] for monitoring the light leaving the resonator is utilized to control the wavelength and/or amplitude of the tuning light signal such that the light leaving the resonator has a predetermined wavelength.

Abstract: Method and apparatus for determining scattering parameters of a scattering matrix of an optical device (34). A method according to the present invention comprises applying an optical stimulus to a plurality of ports (40, 42) of the optical device (34), measuring optical fields emerging from the plurality of ports (40, 42) in amplitude and phase, and calculating the scattering parameters using the measured optical fields. The applying step includes applying the optical stimulus to the plurality of ports (40, 42) simultaneously. The method ensures a consistent phase reference for measurement of all of the scattering parameters so that all measurable characteristics of the device (34) can be calculated directly from the scattering parameters.

Abstract: A tunable optical cavity[10, 100] constructed from a fixed mirror[14, 114] and a movable mirror. The fixed mirror[14, 114] is attached to a substrate[25, 103] having a first electrically conducting surface. A support member[15-18, 119] having the moveable mirror[13, 113] supported thereon and having a second electrically conducting surface, is suspended above the substrate[25, 103]. A circuit[22] applies an electrical potential between the first and second electrically conducting surfaces thereby adjusting the distance between the fixed and movable mirrors. The fixed mirror[14, 114] and the moveable mirror[13, 113] are positioned such that the mirrors form the opposite ends of the optical cavity[10, 100]. The distance between the fixed mirror[14, 114] and the moveable mirror[13, 113] is a function of the applied electrical potential. The support member[15-18, 119] has physical dimensions that are chosen such that the amplitude of thermally induced vibrations in the support member[15-18, 119] are less than 0.01 percent of the wavelength of the resonating light. The support member[15-18, 119] is preferably a thin film membrane having the moveable mirror[13, 113] attached thereto and having openings[115] communicating between the top and bottom surfaces of the membrane. The openings[115] are located so as to reduce the vibration amplitude of the moveable mirror[13, 113] at any mechanical resonances of the membrane. The openings[115] occupy less than 90% of the surface area of the membrane.
