Abstract: Disclosed is a semiconductor optical emitter having an optical mode and a gain section, the emitter comprising a low loss waveguide structure made of two alternating layers of semiconductor materials A and B, having refractive indexes of Na and Nb, respectively, with an effective index No of the optical mode in the low loss waveguide between Na and Nb, wherein No is within a 5% error margin of identical to a refractive index of the gain section and wherein the gain section is butt-jointed with the low loss waveguide, and wherein the size and shape of the optical mode(s) in the low loss waveguide and gain section are within a 10% error margin of equal. Desirably, at least one of the semiconductor materials A and B has a sufficiently large band gap that the passive waveguide structure blocks current under a voltage bias of 15 V.

Abstract: Disclosed are the method and system to derive the wavelength/frequency information covering wide wavelength or frequency range. Its practical applications include both fixed wavelength optical signal and wide bandwidth tunable or non-tunable optical signal, where the wavelength/frequency information is necessary for optical signal calibration, control, and monitoring, optical communications, and data processing. The approach has a “self-compensation” feature which is preferred to improve the accuracy of the extracted wavelength or frequency information even though there are components in the system having strong wavelength or frequency dependence in the wide wavelength or frequency range. The method is generic which can be realized in free space, fiber, or photonic integrated circuit (PIC).

Abstract: A tunable laser assembly housed in a single enclosure and a method of control is described wherein the tunable laser, pump and semiconductor optical amplifier do not share a common optical axis but are all aligned to optical waveguides on an intervening planar lightwave circuit (PLC). Wavelength monitoring circuitry is included on the PLC to enable monitoring and control of the tunable laser center wavelength and optical bandwidth. The design of the PLC does not introduce perturbations into the swept-source laser output spectrum that would cause artifacts in imaging applications such as optical coherence tomography (OCT).
