First Electrically Pumped 1.3 Micron Vertical Cavity Diode.(Brief Article)
Nova Crystals (Tel: 408/434-6682, Website: www.novacrystals.com) has demonstrated the worlds first practical, electrically pumped, 1.3 micron vertical cavity surface emitting laser diode (VSEL) with the highest power reported to date. The device is designed to deliver all of the operating characteristics necessary to enhance telecom/datacom transmission applications. These will include a continuous wave output of 1 mW (without active cooling), a bandwidth of 2.5 Gbps, and an operating voltage of less than 2 V. The source, according to the company, is inherently reliable (up to 100C), robust enough for commercial use, and lends itself to low-cost, high volume manufacture.
