Current fiber optic links designed for high dynamic range applications use distributed-feedback (DFB) semiconductor lasers that only operate over a narrow temperature range. Thermoelectric coolers ar ...

Ortel proposes to investigate methods of performing closed loop control of optically linearized modulators for use in externally modulated analog fiberoptic links. These links are becoming more ...

A high-power cw optical source at 1550 nm is a key component of an externally modulated optical transmitter for future optical networks. Due to its high efficiency, reliability, and compact size, an ...
