Cascadability of Uniform Fibre Bragg Grating for 40 Gbit/s RZ-OOK to NRZ-OOK Conversion

The cascadability of uniform fibre Bragg grating for 40 Gbit/s return to zero on-off keying to non-return to zero on-off keying format conversion has been shown using OptSim simulation program. The main idea of this approach is use of specially designed uniform fibre Bragg grating with appropriate transfer function for shaping of 40 Gbit/s return to zero on-off keying optical spectrum.

Spectrum-Sliced WDM Using OOK Transmission

This chapter presents one of the primary contributions of this dissertation: a mathematical model to analyze and evaluate noise-like spectrum-sliced systems which employ conventional PIN receivers, or as proposed in this dissertation, optical preamplifier receivers. As discussed in previous chapters, spectrum-slicing provides a low-cost alternative to the use of multiple coherent lasers for WDM...

Simultaneous RZ-OOK to NRZ-OOK and RZ-DPSK to NRZ-DPSK format conversion in a silicon microring resonator.

Simultaneous RZ-OOK to NRZ-OOK and RZ-DPSK to NRZ-DPSK modulation format conversion in a single silicon microring resonator with free spectral range equal to twice the signal bit rate is experimentally demonstrated for the first time at 41.6 Gb/s. By utilizing an optimized custom-made microring resonator with high coupling coefficient followed by an optical bandpass filter with appropriate band...

OOK Transmitter in 32 nm DG FinFET Technology

There are several 60 GHz transceiver architectures that have been explored and reported in the past employing the On Off Keying (OOK) Modulation. All of these designs are primarily based on the conventional bulk CMOS architecture. In this paper, we propose a power efficient double gate (DG) MOSFET based OOK Transmitter in 32 nm DG FinFET technology. The proposed novel OOK modulator consists of ...
