Abstract

A high-speed optical receiver for IM-DD 226.875-Gbit/s/

$\lambda $

transmission was designed and fabricated by using high-frequency, integrated flip-chip (FC) mounting. Thanks to the developed FC-mounting technique, the optical receiver exhibited high 3-dB bandwidth and less-fluctuation optical-to-electrical (O/E) frequency response. The fabricated optical receiver demonstrated 3-dB bandwidth of 55.1 GHz with less-fluctuation O/E frequency response up to 50 GHz (i.e., Nyquist frequency under 100-Gbaud operation at 4-PAM modulation frequency). The simulated transmission performance of the optical receiver reveals that its link budget for 226.875-Gbit/s/

$\lambda $

transmission is expanded by 3.7 dB by using the developed FC-mounting technique. The fabricated optical receiver also experimentally demonstrated transmission of a 226.875-Gbit/s signal over 20-km SSMF.

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
