Conference Paper: A silicon photonics platform with heterogeneous III-V integration[Show abstract] [Hide abstract]
ABSTRACT: We present a silicon photonics platform combining silicon processing and heterogeneously integrated III-V materials. This enables passive and active photonic functions on silicon, such as waveguides, filters, modulators, photodetectors and lasers.Integrated Photonics Research, Silicon and Nanophotonics; 01/2011
Conference Paper: An ultra-small, low-power all-optical flip-flop memory on a silicon chip[Show abstract] [Hide abstract]
ABSTRACT: A 7.5pm-diameter InP microdisk laser, integrated on an SOI waveguide is demonstrated as all-optical flip-flop working in continuous-wave regime with an electrical power consumption of several mW, and allowing switching in 60ps with pulses of 1.8fJ.Optical Fiber Communication (OFC), collocated National Fiber Optic Engineers Conference, 2010 Conference on (OFC/NFOEC); 04/2010

ABSTRACT: We demonstrate the use of heterogeneously integrated microdisk lasers for application in low-power and high-speed all-optical flip-flops and gates. Flip-flop operation is experimentally demonstrated using pulse energies of 1.8 fJ in lasers with a diameter of 7.5 µm. Potential optimization of the performance and future photonic integrated circuits are also described.
