Abstract

Over the past few years, vertical cavity surface-emitting lasers (VCSELs) have been shown to have significant potential in areas such as optical communication, computing and interconnection. Presently, temperature improvements are being sought in order to provide more reliable devices that are able to operate uniformly without the need of heal dissipating apparatus. Here, we implement several design strategies and achieve over 120°C cw lasing with more than 2.0mW of optical power at 90°C Moreover, we control threshold currents to a relatively constant value, varying only ±0.45 mA (15%) over a large temperature range of 80°C.
