II-VI Incorporated Introduces 400 mW Micro-Pump Laser for High-Temperature Operation in Next-Generation Coherent Transceivers

September 18, 2019
II‐VI Incorporated (Nasdaq:IIVI), a leading provider of pump laser modules for optical amplifiers, today announced the introduction of its 400 mW micro-pump laser for high-temperature operation. Next-generation coherent transmission applications continue to demand amplifiers that can operate efficiently in space-, power- and thermally-constrained environments.  II-VI’s industry-leading single-mode uncooled micro-pump laser maintains a high output power of 400 mW, with only 1 Watt of power consumption, in environments where temperatures can reach 85 degrees Celsius. “Last year, we nearly doubled the...
