High temperature 1300 nm VCSELs for single-mode fiber-optic communication

Gore Photonics has reported a new long-wavelength VCSEL structure that employs an electrically pumped short-wavelength VCSEL optical pump to drive a 1300 nm VCSEL, as an alternative to direct current injection. In this paper, we provide an update on the recent progress of devices using this structure. In addition to improving power, temperature performance, and speed, our efforts have been focused on making reliable, mechanically robust devices compatible with standard packages.
