We demonstrate an ultra-short cavity 1.5-μm single-mode directly-modulated VCSELs with record modulation bandwidth of 22 GHz at room temperature operation.
Type-II InP-based light sources provide a promising concept for mid-infrared lasers. These have recently made huge progress, as the first electrically and optically pumped lasers could be… (More)
Single-mode 1.5-μm InP-based vertical-cavity surface-emitting lasers (VCSELs) with a 1.5-λ-long semiconductor cavity and two dielectric distributed Bragg reflectors (DBRs) are presented. The… (More)
In this work, we present three different approaches with the objective of increasing the small-signal modulation bandwidth of InP-based VCSELs beyond 20 GHz. The intrinsic bandwidth limitations are… (More)
Quantum optical circuits can be used to generate, manipulate, and exploit nonclassical states of light to push semiconductor based photonic information technologies to the quantum limit. Here, we… (More)
We demonstrate a double-mesa short-cavity 1.5-μm single-mode directly-modulated VCSELs with modulation bandwidth above 20 GHz at room temperature operation.
We demonstrate an all-VCSEL based 100-Gb/s polarization-division-multiplexed 4-level pulse-amplitude-modulation coherent system using two directly modulated 1.55-μm single-mode VCSELs at the… (More)
We present stationary and modulation characteristics of a short-cavity vertical-cavity surface-emitting laser (VCSEL) with 17 GHz bandwidth and emitting at 1.55 µm. The results of several bit-error… (More)
Long-wavelength lasers, emitting above 2 µm, are attractive light sources for trace-gas sensing systems with tunable diode-laser absorption spectroscopy (TDLAS). Here, GaSb-based lasers are perfectly… (More)
A systematic experimental analysis of the stationary and dynamic performance of 1.5-μm InP-based vertical-cavity surface-emitting lasers with two dielectric distributed Bragg reflectors is presented.… (More)
