Organic materials combined with strongly-guiding silicon waveguides have led to a new generation of low-power, high-speed linear-electro optic modulators. In this paper we review the so-called silicon-organic hybrid approach and the more recent plasmonic successor.
In this paper, we propose and experimentally verify that optical filters with fast linear roll-off property, when incorporated in an optical transmitter, can minimize not only the fading effect commonly observed in high bit rate, long distance fiber links, but also improve the link Carrier-to-Noise ratio, and at the same time can maintain the 3rd order inter-modulation distortions at a relatively...
This work reports the wide temperature range operation of 1310 and 1490 nm DFB lasers composed of InGaAsP/InP buried heterostructures. Ultrawide temperature range single mode operation has been demonstrated in 1310 nm DFB lasers covering -70deg to +110degC and 1490 nm lasers covering -45deg to +125degC. The lasers show other excellent performances such as high optical power, high modulation frequency,...
A frequency doubling approach for optical generation of tunable microwave and millimetre-wave signals is proposed and verified experimentally. The experimental setup is based on an optical phase modulator and a simple uniform fibre Bragg grating. The generated signal is of high quality and can be tuned.
