Optical Injection and Lasing Dynamics in Long-Wavelength VCSELs With Intracavity Patterning

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

We present the static and optical injection response of wafer-fused long-wavelength VCSELs with and without intracavity patterning. It is found that the extra optical cavity patterning increases the gain anisotropy between orthogonal polarization modes, in ...

Effect of Cavity Lifetime Variation on the Static and Dynamic Properties of 1.3-μm Wafer-Fused VCSELs

Elyahou Kapon, Alexei Sirbu, Vladimir Iakovlev, Grigore Suruceanu, Alexandru Mereuta, Andrei Caliman, Zlatko Mickovic, Dalila Ellafi

We investigate experimentally the impact of photon cavity lifetime variations on the static and dynamic performance of high-speed 1.3-mu m wavelength wafer-fused vertical-cavity surface-emitting lasers (VCSELs). The photon lifetime is modified by decreasin ...

Control of cavity lifetime of 1.5 mu m wafer-fused VCSELs by digital mirror trimming

Elyahou Kapon, Alexei Sirbu, Vladimir Iakovlev, Grigore Suruceanu, Alexandru Mereuta, Andrei Caliman, Zlatko Mickovic, Dalila Ellafi

Digital chemical etching is used to trim the output mirror thickness of wafer-fused VCSELs emitting at a wavelength near 1.5 mu m. The fine control of the photon cavity lifetime thus achieved is employed to extract important device parameters and optimize ...
