Abstract
Recently we have reported (1) the achievement of laser action in a novel surface emitting laser (SEL) diode using transverse junction and buried heterostructure. Because of the effect confinement of the injected carriers and optical field of this novel SEL structure, a cw low threshold current operation in the range of a few mA was observed. This SEL has a short distributed feedback-type optical resonator and its emission spectrum showed a distinct characteristic with a seemingly wide mode spacing. In this report we present the results of an experimental investigation on the characteristic emission properties of this SEL, and compare the results with a theoretical model based on the actual device structure. A fairly good agreement between the experimental results and theoretical predictions was obtained.
