We propose and demonstrate a modelocked bi-directional VECSEL with a double V cavity configuration. The laser generates 1.04 mum optical pulses with a 0.76 GHz repetition rate and a total average output power of 4 mW.
We demonstrate adjustable chirp of directly-modulated injection-locked VCSELs at 10-Gbps resulting from a novel data pattern inversion phenomenon, which leads to chromatic dispersion compensation and a 10X distance increase over standard single-mode fiber.
We report the first experimental observation of different forms of wavelength polarization switching and bistability with a 1550-nm VCSEL operated just above threshold and subject to orthogonally-polarised optical injection.
Analysis of spectral condensation in a VECSEL with a near-antiresonant gain structure incorporating InGaAs/GaAsP quantum wells emitting around 1030 nm shows the effective FWHM gain bandwidth of this laser to be 32 nm.
We experimentally realized a diffractive unstable laser resonator with a Gaussian shaped outcoupled beam. The structured mirror is assembled with a VECSEL which produces a high beam quality even for the highest amplifier gain.
We report a 2 GHz mode locked vertical external cavity surface emitting laser using a hybrid metal-metamorphic Bragg mirror on the gain structure with a resonant two quantum wells GaInNAs semiconductor saturable absorber mirror (SESAM).
We propose and experimentally demonstrate for the first time a communication system scheme with an OIL-VCSEL acting both as a transmitter and as a receiver, under an identical forward-bias condition.
Thermoreflectance microscopy is used for simultaneous, spatially-resolved temperature measurements of VCSELs in a 1D array. Significant thermal effects such as thermal coupling between neighboring VCSELs and temperature distribution across the apertures are reported.
We experimentally demonstrate deterministic polarization mode control in VCSEL utilizing a single-layer high-index-contrast subwavelength grating mirror. Orthogonal polarization suppression ratio of 36 and 28 dB was obtained under both CW and large-signal pulsed operation.
