Evaluation of the frequency stability of a VCSEL locked to a micro-fabricated Rubidium vapour cell

Yves Pétremand

We present our evaluation of a compact laser system made of a 795 nm VCSEL locked to the Rubidium absorption line of a micro-fabricated absorption cell. The spectrum of the VCSEL was characterised, including its RIN, FM noise andline-width. We optimised th ...

Electrical Modeling of Long-Wavelength VCSELs for Intrinsic Parameters Extraction

Elyahou Kapon, Vladimir Iakovlev

We present an efficient method to model the small-signal modulation response of a long-wavelength VCSEL chip using an equivalent electrical circuit. This circuit serves two distinct purposes. Based on T-Matrix formalism, it is used to remove the parasitics ...
