  • Abstract
    The threshold has been reduced and +0.2 degrees C pulsed operation (Ith=150 mA) has been obtained for a flat surface buried heterostructure 1.3 mu m surface emitting laser. An in situ optical thickness monitor system was introduced into an electron beam evaporator to improve the optical thickness accuracy. 98-99% reflectivities have been obtained in Si/SiO2 multilayer reflectors.
