Abstract :
Summary form only given.Bipolar cascade lasers (BCLs) are capable of demonstrating voltage, incremental resistance, and differential slope efficiencies that are ideally the sum of the individual laser junctions in the cascade. The first room temperature (RT), continuous wave (CW) performance a BCL was recently reported with a record demonstrated differential slope efficiency of 99.3%. We have determined the characteristic temperatures of bipolar cascade lasers and found them to compare well with published data for conventional devices of similar material composition.
