| Abstract: | Thermal crosstalk in a diode array has been investigated using a time-resolved technique. The transmission of a probe beam injected into any of the array diodes is measured while one of them is alternatively switched on and off. The dynamics of temperature evolution of each diode and the thermal crosstalk owing to lateral heat spreading are deduced from temperature-induced Fabry-Perot oscillations. |
