Integrated Silicon Photonic Laser Sources for Telecom and Datacom
Integrated Silicon Photonic Laser Sources Telecom Datacom
2014/11/6
We demonstrate record performance heterogeneously integrated telecom wavelength and datacom wavelength lasers, processed simultaneously on the same wafer. Tunable lasers for telecom applications and u...
50 fJ-per-bit, High Speed, Directly Modulated Light Sources for On-chip Optical Data Communications
50 fJ-per-bit High Speed Directly Modulated Light Sources On-chip Optical Data Communications
2015/5/20
By employing optical injection-locking the direct modulation bandwidth of a 10μm diameter disc laser is increased to 15GHz. In addition, modulation at 20Gb/s is demonstrated with only 1mW DC bias & 19...
24 channels colorless WDM-PON with L-band 10 Gb/s downstream and C-band 2.5 Gb/s upstream using multiple- wavelengths seeding sources based on mode-locked lasers
Fiber optics optical communications Optoelectronics Networks
2015/6/8
A novel WDM-PON delivering 10-Gb/s downstream based on L-band loss-less reflective-amplified-modulator and 2.5-Gb/s upstream based on C-band injection-locked Fabry-Perot laser is experimentally demons...
2.5 Gbps Operation of RSOA for Low Cost WDM-PON Sources
Operation RSOA Cost WDM-PON Sources
2015/7/17
We present design issue of RSOA and report fabricated-device/packaged-module characteristics for WDM-PON. Optical gain, 3dB ASE bandwidth and polarization dependent gain were about 25 dB, 35 nm and le...
Spectrum Sliced Sources AMOOFDM Modulated for WDM&TDM PON
Spectrum Sliced Sources AMOOFDM Modulated WDM&TDM PON
2015/7/16
We experimentally demonstrate the use of AMOOFDM format as a cost effective solution for colorless source WDM-PONs based on spectrally sliced ASE source (SLED, RSOA and pre-selected RSOA).
Transmission Performance Improvement Studies for Low-Cost 2.5 Gb/s Rated DML Sources Operated at 10 Gb/s
Transmission Performance Improvement Studies Rated DML Sources Operated
2015/7/31
Performance improvement methods for the operation of 2.5Gbps rated low-cost DML sources at 10Gbps over record distances are studied by means of chirp characteristics, offset receiver filtering and DFE...
