The NeoPhotonics External Cavity ITLA combines extremely narrow linewidth, low phase noise, high output power, and accurate frequency control, making it well suited for 100 Gbps and beyond applications. The long cavity length of our External Cavity Laser (ECL) gives a pure optical signal with the narrowest linewidth in the industry. In coherent systems, any error in the phase of the signal and reference lasers, as represented by that laser’s linewidth, will cause errors in the extracted phase information from the signal. Consequently, lasers with stable phase or, equivalently, a narrow linewidth, become critical, especially for higher order modulation schemes such as 16QAM and 64QAM.
