Abstract

We present a novel scheme for generating high energy ultrashort pulses in modelocked semiconductor lasers using a fast saturable absorber based upon intersubband transitions (ISBT) in GaN/AlGaN superlattice. The fast electron relaxation time (~100-300 fs) in this saturable absorber enables the generation of stable sub-100 fs pulses at the communication wavelength (1.55μm) with high pulse energies (5-10 pJ).
