Epson has developed a new vertical cavity surface emitting laser (VCSEL) for use as a laser light source in optical data communications.

According to the company, the S92A1A00 VCSEL is a highly reliable, low-power, oxide VCSEL that achieves transfer speeds as high as 5GBps at a threshold current of 1.2mA. It has a 850nm laser wavelength and multimode laser oscillating mode.

With a 5mA operating current, the device features an operating voltage of 1.85V, optical output of 2.7mW, slope efficiency of 0.7mW/mA, and beam divergence of 25. Chip dimension is 0.3(L)-by-0.3(W)-by-0.2(T)mm.

A VCSEL, the company explained, is a type of semiconductor laser that emits laser light vertically from the surface of a chip. Because they can be driven at high speeds and at low power levels, VCSELs are widely regarded as the suitable light source for short-range optical data communications.

Samples of the S92A1A00 will become available in September. Epson will begin accepting volume production orders in December 2004.

The new VCSEL will also be on display at the Epson booth at InterOpto '04, an international optoelectronics exhibition that starts on July 13 at the Makuhari Messe in Chiba, Japan.
