InP-based type-II quantum wells are a promising concept for long wavelength lasers beyond 2 μm. In this paper, recently developed vertical-cavity surface-emitting lasers for 2.5 μm with type-II quantum wells are introduced and their performance is discussed. These lasers demonstrate single-mode CW operation with an output power up to 400 μW and side-mode suppression ratio of 30 dB. The maximum temperature...
This work shows different approaches to cover the spectral range from 2 to 4 µm with active regions based on InP and GaSb for devices suitable as light sources for gas-sensing applications. For shorter wavelengths up to 2.3 µm type-I InP-based quantum wells with rectangular and triangular shape are the preferred choice, beyond that GaSb-based type-I active regions were studied to cover the wavelengths...
