Sub-kHz-Linewidth External-Cavity Laser (ECL) With Si3N4 Resonator Used as a Tunable Pump for a Kerr Frequency Comb

Tobias Kippenberg, Junqiu Liu

Combining optical gain in direct-bandgap III-V materials with tunable optical feedback offered by advanced photonic integrated circuits is key to chip-scale external-cavity lasers (ECL), offering wideband tunability along with low optical linewidths. Exter ...

Ultrafast tunable lasers using lithium niobate integrated photonics

Tobias Kippenberg, Rui Ning Wang, Guanhao Huang, Anat Siddharth, Mikhail Churaev, Viacheslav Snigirev, Junqiu Liu

Early works(1) and recent advances in thin-film lithium niobate (LiNbO3) on insulator have enabled low-loss photonic integrated circuits(2,3), modulators with improved half-wave voltage(4,5), electro-optic frequency combs(6) and on-chip electro-optic devic ...

Exploring nonlinearities in multimode optical fibers for lasers and computing

Ugur Tegin

Multimode optical fibers are the backbone of telecommunication and medical imaging. When light with high intensity travels through a multimode fiber, photons and matter start to interact and propa-gation becomes nonlinear. The nonlinear propagation of ligh ...

Mode Coupling Measurement in Dual-Frequency Quantum Well-based VECSEL

Elyahou Kapon, Alexandru Mereuta, Andrei Caliman

We experimentally investigate the Lamb coupling constant C in InGaAlAs Quantum Wells active medium. An Optically-Pumped Vertical-External-Cavity Surface-Emitting Laser emitting at 1.54 mu m is designed to sustain the oscillation of two orthogonally polariz ...

Polarization mode control of long-wavelength VCSELs by intracavity patterning

Elyahou Kapon, Benjamin Dwir, Alexandru Mereuta, Vladimir Iakovlev, Alexei Sirbu, Andrei Caliman, Zlatko Mickovic, Christopher Michael Long

Polarization mode control is enhanced in wafer-fused verticalcavity surface-emitting lasers emitting at 1310 nm wavelength by etching two symmetrically arranged arcs above the gain structure within the laser cavity. The intracavity patterning introduces bi ...

Optical Soc Amer2016

We report the first efficient spin injection in a CW optically pumped VECSEL, obtained with phase anisotropy dynamic control. A threshold reduction of 1.5 % and an ellipticity of 75% are obtained at RT. Theoretical and experimental investigation of the pol ...
