We report the demonstration of an ultra-compact 5-channel hybrid integrated III-V/Si transmitter. We successfully achieved modulation up to 40 Gbit/s/channel providing a total aggregated capacity of 200 Gbit/s and transmission over 10 km at 21.4 Gbit/s/channel for 100Gbit/s.
We reported the first hybrid Ill-V/Si integrated QPSK wavelength-tunable transmitter based on high-speed ring modulators (BW∼23GHz). 80 Gbit/s PDM-QPSK signal transmission over 100 km with said integrated hybrid transmitter as well as a fully packaged silicon-based coherent receiver is demonstrated.
We review recent advances on hybrid III-V/Silicon devices using edge coupling. Design of external silicon cavities enables the realization of a broad range of on-chip functionalities as well as advanced hybrid transmitters.
We demonstrate a novel hybrid Ill-V/Si laser, which exhibits high fiber-coupled output power without booster SOA (up to +13 dBm at certain wavelengths) and a record tuning range (95nm) over the C and L band with side mode suppression ratio greater than 35 dB.
We review the recent achievements done in optical slot switched technology using silicon-based photonic integrated circuit. Monolithic integrated slot-blocker and a dual-hybrid cavity laser for fast wavelength switching are reported.
We propose a novel hybrid silicon-based laser with integrated variable reflectivity mirror. The single-ring laser is tunable over 10 nm with high SMSR. The adjustment of the mirror reflectivity allows controlling lasers characteristics.
We propose a bidirectional reflective semiconductor optical amplifier as promising solution for on-chip amplification with silicon photonic integrated circuit. Small form factor device, wide optical bandwidth and high optical fiber-to-fiber gain are presented.
We designed and fabricated a fast-wavelength-tunable hybrid laser diode using two selectable silicon photonic Vernier ring-based cavities. Single mode operation (SMSR > 30 dB) over more than 35 nm and switching speed of 35 ns are demonstrated.
We report on a fully integrated 16-channel polarization diversity fast slot-blocker with 100 GHz channel spacing using silicon photonics. We demonstrated extinction ratio of 20 dB and switching time of 10 ns timescale allowing add-drop operation as high as 320 Gbit/s PDM-32QAM signals.
A novel 16-channel digitally wavelength-tunable laser is proposed and experimentally demonstrated using a semiconductor optical amplifier and silicon photonic integrated circuit. The device exhibits a laser threshold below 45 mA, SMSR around 20–25 dB and nanosecond switching time.
We demonstrate a novel fully integrated, silicon-on-insulator, 16-channel polarization diversity fast reflective slot-blocker with nanosecond switching time, integrating more than 65 functional elements. Its suitability for use in reconfigurable metropolitan networks is assessed.
We experimentally evaluate performances of QPSK, 8- and 16-QAM signals after traversing a long cascade of up to 50 SOAs and assess system design rules for an optical packet-switched SOA-based network.
Recent progress on hybrid integration of III–V on Silicon devices using wafer bonding is presented focusing on hybrid tunable lasers and their applications for the next generation of access, metropolitan and long haul optical networks.
We propose a novel cost efficient node architecture for a wavelength division multiplexed packet-switched network based on reflective integrated device. We demonstrate a 16-channel, silicon-on-insulator, reflective monolithic integrated slot-blocker that integrates one arrayed waveguide grating, 16 variable optical attenuators, 16 Bragg grating mirrors and one vertical fiber coupler. Small-form factor...
We introduce here the novel 2D Non-Quadrature Intensity Modulation Formats (NQIM) generated with two phase-shifted intensity modulators. We particularly highlight 4–8 symbol Diamond 2π/3 — NQIM formats as spectrally efficient and noise tolerant candidates for integrated transmitters.
In dispersion-unmanaged 100-Gbit/s single-channel transmission, the one-to-one relationship between error-rate and noise variance does not hold at high powers. More accurate error assessment than with Gaussian modeling can be obtained by involving high order statistics.
We study the generation of novel 2D modulation formats (N-QIM) based on intensity modulations with prefixed optical phases. Such new scheme is implemented with InP photonic integration and compared to 2ASK–2PSK modulation format.
We demonstrate a 16-channel, silicon-on-insulator, monolithic integrated slot-blocker. This silicon photonic circuit includes two arrayed waveguide gratings, 16 variable optical attenuators and two vertical fiber couplers. We successfully operate it with 56 Gb/s and 80 Gb/s QPSK optical packets.
We demonstrate a low cost tunable transmitter based on a directly modulated hybrid III-V/Si laser with enhanced modulation bandwidth. We successfully achieve 21.4 Gbit/s direct modulation including FEC overhead on 12 wavelengths over a short-reach access link (10-km).
In a novel concept for intra-datacenter networks, we combine optical slot switching and elastic, burst-mode transponders, with variable bit-rate from 100 to 250 Gb/s depending on node count. Our scenario requires ∼x400 fewer transponders than today's 10 Gb/s electronic networks
