Gain measurement of high characteristic temperature 1.3 mu m GaInAsP/InP strained-layer quantum well lasers with temperature dependent reflectivity (TDR) mirror

摘要

By comparing the optical gain of 1.3 mu m strained-layer quantum well lasers with characteristic temperatures T/sub 0/ of 150 K (high) and 60 K (typical), it is found that temperature insensitive net gain plays an important role in reducing the temperature sensitivity of the threshold current. The resonance frequency for high T/sub 0/ lasers exhibits temperature insensitivity, resulting from the temperature insensitive net gain characteristics.
