WebDec 3, 2013 · 4. Conclusions. In conclusion, electro-absorption from GeSi on Si is one of the most promising candidates to realize a compact, low-energy, fast, temperature stable and high-volume optical modulator for short distance optical interconnects. High performance optical modulators have been demonstrated by both FKE and QCSE. WebLumentum manufactures indium phosphide (InP) externally-modulated lasers (EMLs) in our internal wafer foundry. These EMLs consist of a distributed feedback (DFB) diode lasers followed by a monolithically integrated electro-absorption modulator (EAM). With a DFB, a distributed Bragg reflector is used to accurately lock to the desired wavelength. terjemah maqsud pdf
