Lateral Integration of VCSEL and Amplifier with Resonant Wavelength Detuning Design

We propose and demonstrate the lateral integration of VCSEL and slow-light waveguide amplifier with in-plane resonant wavelength detuning design, enabling the unidirectional coupling. A record quasi-single-mode power (>27mW) with narrow beam divergence (<0.06°) is presented. © 2019 The Author(s)
