摘要： A multiplexer and demultiplexer may be formed so that two input wavelengths from an optically multiplexed signal may be demultiplexed. A demultiplexer may be in the form of an integrated filter and photodetector. The filter may reflect one wavelength and may pass another wavelength. The reflected wavelength is detected by a first detector and the passed wavelength is detected by a second detector. For example, the second detector may be combined with the filter by forming the filter directly on the second detector. In one embodiment, the second detector may be L-shaped.

摘要： A chip-based planar Raman spectroscopic measurement system is disclosed comprising at least a semiconductor laser as excitation light source, an output waveguide coupling and delivering laser light out of chip, a photo-detector monitoring the laser optical power, an input waveguide coupling signal light to chip, a planar spectrometer comprising Planar Waveguide Grating (PWG) and an array photo-detectors, and control electronics. In some embodiments the PWG is a fixed frequency Arrayed Waveguide Grating (AWG), the laser is frequency-tunable. In other embodiments, the laser has fixed frequency, the PWG or the AWG is frequency tunable. In either case, the frequency tunability will ensure the recapture of the spectral information missed due to the spectral characteristics of the planar waveguide grating such as the channel spacing of the AWG, resulting in high channel count and high-resolution Raman measurement of sufficient spectral range.

摘要： Exemplary embodiments provide wavelength selective and tunable laser devices and a method for tuning the laser devices. An exemplary laser device, which can be operated in a single-wavelength lasing mode at a selectable and tunable lasing wavelength, includes a multi-mode laser, a feedback portion, and a wavelength tuning structure. The laser generates an optical emission having a spectrum that peaks at a plurality of discrete wavelengths. The feedback portion includes an optical etalon arranged to provide wavelength selective feedback to the laser to generate a beam of laser light at a lasing wavelength selected from the plurality of discrete wavelengths. The wavelength tuning structure provides tuning of the lasing wavelength by locally adjusting a refractive index of the channel waveguide to adjust the spectrum of the optical emission, where the wavelength tuning structure adjusts the spectrum of the optical emission to overlap a transmission spectrum of the etalon at the lasing wavelength.
