Abstract

Optical gain measurement is extended to chips designed for external cavity lasers, where facet reflectivity is intentionally kept null, which prevents from any application of the Hakki-Paoli method. The new method is first shown to be consistent with the standard methods, by applying it to a chip with Fabry-Perot resonances and comparing the results of the new and the Hakki-Paoli method. The validated new method is then applied to the non-reflecting cavity of a tunable laser diode based on external cavity.
