High Speed 1300 nm Vertical Cavity Surface Emitting Laser

Vertical cavity surface-emitting lasers (VCSELs) have generated a great deal of interest due to the potential cost and performance advantages of the vertical structures. VCSELs operating at 850 nm have already entered the commercial market, while long wavelength (1300/1550 nm) VCSELs have lagged in their development. A few groups have demonstrated room-temperature continuous wave (CW) operation [1,2,3], with the highest output power (0.5 mW @ 25°C) and operating temperature (64°C) achieved at 1550 nm [1]. In this work, we describe 1300 nm VCSELs with an integrated 850 nm VCSEL optical pump [4].
