Dual-wavelength lasers on generic foundry platform
Abstract
We propose and implement four simple and compact dual-wavelength laser concepts integrated in a Photonic Integrated Circuit (PIC) based on a InP generic foundry platform. In a first step, we arrange two detuned Distributed-Bragg-Reflectors (DBR) in either a sequential or in a parallel order, acting as narrowband wavelength selective cavity mirrors. In a second step, we close the cavities by using either a third DBR or by using a Multimode-Interference-Reflector (MIR). We present LI-characteristics and optical spectra emitting around 1550~nm with wavelength separations of 1~nm or 10~nm and evaluate their particular potential for simultaneous dual-wavelength emission. In addition, we find either one or multiple equal power points as well as complete switches when the gain current is being tuned. We discuss the characteristics and limitations of each concept including arranging the detuned DBRs in a sequential or parallel order.
