We describe the design and results of several hybrid silicon devices that combine benefits of III-V semiconductors with silicon-based platforms. Presented work includes a silicon-on-insulator evanescent phase modulator and a recirculating buffer using silica waveguides.
In this talk we review the latest progress on the DOD-N LASOR optical router project. Architectural studies including design and buffering will be discussed as well as prototype node performance. Recent results in integration in InP and Si/InP platforms will be described.
The first quantum dot based crossbar switch matrix is proposed, fabricated and demonstrated at a wavelength of 1.55 mum. Power penalty measurements at 10 Gb/s show minimal path dependence with values of 0.4 to 0.6 dB.
This paper reviews the recent advanced optical transmission technologies that have the potential to expand substantially the optical transparent network domain. The new challenges that these emerging technologies bring to optical packet switching design are discussed.
Biased current and temperature dependence of amplified spontaneous emission injection-locked reflective semiconductor optical amplifier based transmitter directly modulated at 622 Mbit/sec and 1.25 Gbit/sec in DWDM-PON system with channel spacing of 200 GHz are characterized.
We have developed a 300-pin optical duo-binary transceiver, which employed a full L-band tunable-laser array and a variable optical attenuator, for L-band DWDM network. Transmission was demonstrated up to a chromatic dispersion of 3000 ps/nm.
A novel wavelength division multiplexing - radio over fiber scheme is proposed with multi optical carrier suppression for simultaneous wired and wireless 1.25 Gbps signal transmission. Many modes of a FP-LD are simultaneously carrier suppressed by Mach-Zehnder modulator and each channel is modulated by a reflective semiconductor optical amplifier. A BER of 10-11 for three channels at 1.25 Gbps are...
An effective configuration, named Mickey NOLM, is presented as an example for multiple and interleaved NOLM structures. Simulations results and possible applications to all optical signal processing are reported and compared to single NOLM ones.
Simultaneous inverted and non-inverted wavelength conversions (WCs) at 10 Gb/s with 2R regeneration are demonstrated using nonlinear polarization rotation in an SOA. A power penalty reduction of 1.2 dB for inverted WC and 0.8 dB for non-inverted WC is obtained at a BER of 10-9.
Comparison on shortened falling-time, reduced chirp and improved on/off extinction ratio of 10 Gbit/s all-optical pulsed RZ generation in single-and multi-wavelength inverse-optical-comb injected semiconductor optical amplifiers with temporally reshaped gain-window is demonstrated.
In order to meet the ever-increasing demand of data communication for future optical networks and optical computing, high-speed photonic digital processing is required. Elementary blocks, performing basic operations are the building elements for more complex subsystems implementing all-optical digital processing. These functions include elementary optical logic gates as well as complex photonic combinatorial...
