L. Davis et al., SMALL-SIGNAL MODULATION AND TEMPERATURE-DEPENDENCE OF THE TUNNELING INJECTION-LASER, Applied physics letters, 64(24), 1994, pp. 3222-3224
Recently, we demonstrated a novel laser structure, called the tunnelin
g injection laser, where the electrons are injected into the active la
sing quantum well region via tunneling. High performance results for t
his device have now been demonstrated. A T(o) of 160 K was found from
temperature-dependent measurements (25-70-degrees-C), High differentia
l gain (5.5 X 10(-16) cm2) and modulation bandwidth (12.5 GHz) have be
en attained relative t) other single quantum well lasers.
