摘要： An optical device is provided having an input and an output terminal spaced equidistant from an optical axis of a graded index lens. An at least partially reflective surface is disposed spaced but adjacent from another end face of the graded index lens. The optical path length from the input or output terminal to a first end face of the lens is equal to the optical path length from the other end face of the lens to the at least partially reflective surface. The graded index lens has a length that collimates light launched from the input terminal to the at least partially reflective surface. Moving the input an output terminals toward or away from one another changes the angle at which light exits the other end face of the graded index lens, and thus changes the angle at which light is incident upon the at least partially reflecting surface. Conveniently, if the at least partially reflecting surface is a WDM interference filter, tunability of the filter is achieved by moving the input an output terminals toward or away from one another.

摘要： A multi-pass Fabry-Perot etalon, or bandpass, filter, has a Fabry-Perot cavity defined by two partially reflective mirrors with a gap therebetween and a third reflecting mirror positioned adjacent said two mirrors and arranged to reflect substantially any light eliting said cavity back into it. The filter can replace two single-pass Fabry-Perot etalon filters and can provide lower signal loss and simpler wavelength control.

摘要： An optical switch has a stepping motor with a fiber faceplate on which are mounted end portions of output optical fibers terminating in GRIN lenses. The end portions are arranged along a pitch circle. The faceplate is spaced from the stepping motor and the diameter of the pitch circle is smaller than the diameter of the stepping motor, the output fibers diverging from the faceplate towards the motor and beyond in a space-saving arrangement. The stepping motor drives a movable arm with attached end portion of an input optical fiber, also with a GRIN lens, into one of a plurality switching positions. The connection between the fibers and the lenses and also the relative axial arrangement of the paired lenses in the switching positions is offset to reduce or minimize the reflection of light transmitted from the input fiber to the output fiber, back to the input fiber.

摘要： A bandpass optical filter is provided that is formed within an optical fiber in the form of a Bragg grating. The grating includes multiple Fabry Perot cavities disposed along the waveguide. Each of the cavities includes a pair of reflectors. Each reflector comprises alternating high-low index regions within the waveguide, each region having a thickness of one quarter-wave at a bandpass wavelength, each alternate region being of a different index of refraction than an adjacent region. A multiple odd quarter-wave or quarter-wave high or low index region is sandwiched between each pair of reflectors. The number of high/low regions within a reflector is selected in accordance with the refractive index difference between two alternate adjacent regions.

摘要： In order to reduce the number of components and avoid relatively long optical lengths, a non-reciprocal device such as a circulator comprises a plurality of ports at one end of the device, a mirror at an opposite end of the device, and a series of optical elements disposed between the ports and the mirror. The optical elements include a first element which spatially separates first and second orthogonally-polarized components of a light beam leaving one of said plurality of ports and passing through the device in a forward direction, and recombines the first and second components as they pass through the device in a reverse direction after reflection. A second optical element, disposed between the separating and recombining element and the mirror, selectively displaces and rotates the light beam components such that the recombined light beam is coupled to a different one of the plurality of ports.
