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： External cavity laser devices provide multimode laser operation by using a wavelength selective element that produces a spectral width profile able to support multiple longitudinal laser modes. The spectral width profile, for example, may have a substantially flat response across multiple longitudinal laser modes, such that no single mode predominates. The wavelength selective elements may be gratings written in waveguides, where the grating's bandwidth as well as the laser cavity length set the number of supported longitudinal laser modes. In some examples, a tuning element may be used to adjust device operation. In further examples, a laser gain region and the wavelength selective element may be angled with respect to adjacent coupling facets to reduce reflection losses within the laser cavity.
