NeoPhotonics offers a high-power version of our industry-leading ultra-narrow linewidth Micro-ITLA with an output power of 17 dBm. High output power is particularly advantageous for systems that use the same laser for the signal and local oscillators. 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.
