摘要： A nanowire-based photodiode and an interdigital p-i-n photodiode use an i-type semiconductor nanowire in an i-region of the photodiode. The nanowire-based photodiode includes a first sidewall of a first semiconductor doped with a p-type dopant, a second sidewall of the first semiconductor doped with an n-type dopant, and an intrinsic semiconductor nanowire that spans a trench between the first and second sidewalls. The trench is wider at a top than at a bottom adjacent to a substrate. The first semiconductor of one or both of the first sidewall and the second sidewall is single crystalline and together the first sidewall, the nanowire and the second sidewall form a p-i-n semiconductor junction of the photodiode.

摘要： A VCSEL 101 comprising an optical cavity having an optical loss and a loss-determining element 117 coupled to the optical cavity. The loss-determining element 117 progressively increases the optical loss of the optical cavity with increasing lateral distance from the optical axis 105. The optical cavity includes a first mirror region 111, a second mirror region 107, a plane light-generating region 125 sandwiched between the first mirror region 111 and the second mirror region 107, perpendicular to the optical axis 105, and an element 113 that defines the lateral extent of the optical cavity in the plane of the light-generating region 125. The first mirror region 111 and the second mirror region 107 are both conductive and have opposite conductivity modes.

摘要： The present invention provides a low noise multimode VCSEL that can be used to transmit data reliably on multimode optical media at data rates up to and exceeding 1 gigabit per second with bit error rates less than 1.times.10.sup.-9 errors/bit. In contrast to conventional multimode lasers where optimal mirror reflectivity is designed for maximum power output, in the present invention mirror reflectivity is increased to a point where the output power is less than half the maximum output power. Preferably, the reflectivity of the first and second mirror regions of the multimode laser is high, typically greater than 99.5%.

摘要： A hybrid guided-mode resonance (GMR) grating, an optical filter and a method of optical filtering employ distributed Bragg reflection. The hybrid GMR grating includes a waveguide layer that supports a GMR having a GMR resonant frequency. The hybrid GMR grating further includes a diffraction grating that couples a portion of a signal incident on the hybrid GMR grating into the waveguide layer; and a distributed Bragg reflector (DBR) that reflects another portion of the incident signal. The coupled portion of the incident signal has a frequency corresponding to the GMR resonant frequency. The reflected portion has a frequency away from the GMR resonant frequency. The optical filter includes the hybrid GMR grating and a coupler. The method includes coupling an optical signal into the hybrid GMR grating and further coupling a reflected signal out of the hybrid GMR grating.

摘要： A modulator having a waveguide and a microdisk resonator is disclosed. The waveguide has an input port for receiving a light signal of wavelength λ and an output port for transmitting modulated light. The microdisk resonator has a resonance at λ and is coupled to the waveguide between the input and output ports such that at least 10 percent of the light traveling in the waveguide is coupled to the microdisk resonator. The microdisk resonator further includes a material having a first state and a second state, the material absorbing more of the light in the first state than in the second state. The first and second states are selectable by a signal that is applied to the microdisk resonator. In one embodiment, the waveguide and the microdisk resonator occupy different portions of a sheet of material having the various layers used to construct the resonator.
