SANTA CLARA, Calif., March 8, 2023 — Developed in partnership with Innolume, Alfalume's O-band high-power InAs/GaAs Quantum Dot DFB  lasers operate at a power level of 250 mW at 85 ºC, without requiring thermoelectric coolers, which can be split into four or eight channels for 800 G and 1600 G DR8 Modules. The lasers have a power efficiency of 20% at 105 ºC and can operate efficiently up to 150 ºC. They are insensitive to feedback up to -15 dB, enabling operation without an optical isolator, and they feature high SMSR, greater than 55 dB. They also feature low relative intensity noise below -155 dB/Hz.
