Uncooled, Full C-Band, Multi-Wavelength DWDM Transmitter enabled by Adaptive Self-Monitoring

This project uses adaptive self-monitoring to enable uncooled operation in a harsh environment of a full C-band, wavelength selectable, multi-wavelength DWDM transmitter. The program will utilize novel sensors integrated into the transmitter module to intelligently monitor and provide feedback to adaptively and independently control the key parameters of the transmitter array. The design will operate over a wide temperature range (0 to 70C) without the use of a thermo-electric cooler (TEC). Phase I will research the feasibility of the approach, including design of sensing elements and appropriate algorithms, experimental verification of sensor concepts and temperature effects on device performance and reliability, and initial design and modeling to create the uncooled Photonic Integrated Circuit (PIC). Phase II will include detailed design and fabrication of the sensors and uncooled PIC, packaging of these devices, and adaptive algorithm development to ensure optimum transmitter performance over the full temperature range.
