摘要： A method and structure for mechanical self-alignment of semiconductor device features, for example multi-chip module features. Alignment of the features can be performed using mechanical alignment grooves within a layer of a first device and mechanical alignment pedestals of a second device. The alignment accuracy is limited by the patterning resolution of the semiconductor processing, which is in sub-micron scale. Flip-chip bonding can be used as the bonding process between chips to increase the alignment precision.

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： An optical transmitter includes an external cavity laser array formed in a PLC, a trench-based detector array and an AWG. The external cavity laser is formed using an array of substantially similar laser gain blocks and an array of gratings formed in waveguides connected to the gain blocks. Each grating defines the output wavelength for its corresponding external cavity laser. Each detector of the detector array includes a coupler to cause a portion of a corresponding laser output signal of the laser array to propagate through a first sidewall of a trench and reflect off a second sidewall of the trench to a photodetector. In one embodiment, the photodetector outputs a signal indicative of the power level of the reflected signal, which a controller uses to control the laser array to equalize the power of the laser output signals.

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.
