Optoelectronic Devices and Related Physical Phenomena in Thin Film Semiconductor Configurations.
Abstract
A research program in semiconductor lasers and related phenomena resulted in new understanding relating to coherent single lobe laser arrays and to structures displaying near-diffraction-limited output. Using our molecular beam epitaxial reactor, we have demonstrated new unstable resonator geometry of semiconductor laser which potentially are capable of producing large aperature high power without the need for arrays. Typical powers of approx. 0.4 Watt were demonstrated in a single mode. Basic theoretical analysis and experiments on noise in semiconductor lasers has resulted in a new quantum formulation which takes into account the amplitude to phase coupling. This coupling is characterized by a new dispersive parameter alpha. Direct measurement of alpha were performed. Keywords: Laser arrays; Optoelectronic devices; Stable resonantor semiconductor lasers.
