Optical frequency combs from ultrafast solid-state and semiconductor lasers
(2020)Proceedings of SPIE ~ Metamaterials, Metadevices, and Metasystems 2020A fully stabilized optical frequency comb provides equally spaced frequencies for a precise ruler in optical frequency metrology. This talk will review recent progress in single and dual comb generation from diode pumped solid-state and vertical emitting semiconductor lasers. A modelocked integrated external-cavity surface-emitting laser (MIXSEL) integrates both the gain and the saturable absorber layer within the same semiconductor wafer ...Other Conference Item -

Passively modelocked VECSEL using a single-layer graphene saturable absorber mirror
(2013)2013 Conference on Lasers & Electro-Optics Europe & International Quantum Electronics Conference CLEO EUROPE/IQECOptically pumped ultrafast vertical external cavity surface emitting lasers (VECSELs), also referred to as semiconductor disk lasers (SDLs), are very attractive sources for ps- and fs-pulses in the near infrared [1]. So far VECSELs have been passively modelocked with semiconductor saturable absorber mirrors (SESAMs, [2]). Graphene has emerged as a promising saturable absorber (SA) for a variety of applications [3-5], since it offers an ...Other Conference Item -
Precise mid-infrared characterization of InGaSb/GaSb SESAMs
(2021)2021 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC)There is a strong interest in mid-infrared (mid-IR) Semiconductor Saturable Absorber Mirrors (SESAMs) [1]. We have established an accurate nonlinear reflectivity and time-resolved SESAM characterization which covers a wavelength range from 1.9 μm to 3 μm transferring our near-IR knowhow [2] , [3] to the mid-IR ( Fig. 1a , 1b ). The nonlinear reflectivity of a SESAM is characterized by the saturation fluence, modulation depth, non-saturable ...Other Conference Item -
Mid-infrared type-I InGaSb/GaSb quantum well SESAM
(2021)2021 Conference on Lasers and Electro-Optics Europe & European Quantum Electronics Conference (CLEO/Europe-EQEC)A Semiconductor Saturable Absorber Mirror (SESAM) is a key optical component used extensively for passively modelocking of diode-pumped solid-state and semiconductor disk lasers. Modulation depth (ΔR), saturation fluence (F sat ), non-saturable losses (ΔR ns ) and recovery times are the key parameters of a SESAM, which depend on semiconductor layer design and growth parameters. It has been shown that the recovery dynamics of InGaSb-based ...Other Conference Item
