Reflective Amplified Modulator Operating at 40 Gbps up to 85ºC as Colorless Transceiver for Optical Access Networks
01 January 2012
In this paper we report a 40 Gb/s operation of Remote Amplified Modulator at the temperature up to 85ºC within the C- and L-band spectral ranges. The device was fabricated using InP monolithic integration platform which relies on AlGaInAs QW active material, gap engineering by Selective Area Growth and low-parasitic RC semi-insulating buried heterostructure. We investigated its high temperature operation capability as well as chirp and Rayleigh scattering effects in a bidirectional transmission. This 40Gb/s remote amplified modulator could operate at fastest short sections of next-generation WDM optical access networks or in WDM routers as a part of colorless transceivers.
