In this paper, the applications of recent developed double side electro-absorption modulated DFB laser (DS-EML) for high speed optical short reach and metro networking will be discussed.
In this paper, we present a novel device which comprises a DFB laser with electroabsorption modulators integrated on both sides. This integrated chip provides two independently modulated optical outputs from a single laser source and thus cuts the required number of chips for multilane applications in half. Both outputs can be simultaneously operated with 56 Gb/s NRZ leading to 112 Gb/s from a single...
A 4×4 MMI 90° optical hybrid for 2 μm is designed, fabricated and characterized using a monolithically integrated MZI. A phase deviation around ±10°, Common Mode Rejection Ratio > 15.6 dB and an excess loss of 2.2 dB are obtained.
