High volume 850nm oxide VCSEL development for high bandwidth optical data link applications

Directly modulated 850nm oxide VCSEL is a key enabling technology for short reach, high speed data-communication applications. Current commercially available optical transceiver products operate at data rate up to 10Gb/s per channel, for aggregate data rate of 70Gb/s and beyond, in the case of parallel optical data link. High volume, low cost, over temperature optical modulation speed, spectral width, output power, thermal power budget, large signal electrical interaction with the IC driver, and reliability are some of the key requirements driving the 850nm oxide VCSEL development. In this paper, we discuss some of the engineering issues investigated for developing a viable oxide VCSEL product operating at 10Gb/s per channel and higher data rate.
