Abstract

In this paper we discuss how a combination of band structure and band alignment engineering may be used to reduce the temperature sensitivity of semiconductor lasers operating in the near-IR. The use of back-to-back type-II band alignment “W”-structures, already successfully demonstrated in the mid-IR, provides a route to engineer the temperature sensitivity of the emission wavelength in near-IR devices through control of the band gap and band bending. Furthermore, utilising novel alloys such as the bismide-nitrides also provides a route to reduce non-radiative processes which underpin the temperature sensitivity of the threshold current across this wavelength range.
