Abstract
This paper presents the development and characterization of high-speed ON-OFF Keying (OOK) Optical Transmitter up to 12 Gbps using External Modulation Technique that comprises Continuous Wave (CW) laser, Mach-Zehnder Modulator (MZM), and ultra-high bandwidth driver amplifier for MZM. The CW laser driver and high bandwidth modulator driver amplifier has been designed and integrated with the modulator which is biased for OOK modulation scheme. This work includes Direct Current (DC), Optical and Radio Frequency (RF) characterization of MZM modulator; selection of suitable bias point for modulator to achieve OOK modulation format, design and development of wideband driver amplifier in microstrip configuration on 25-mil alumina using Hittite device. The biasing circuit for distributed feedback laser is designed as an unmodulated CW optical signal to feed optical modulator. In this work, the assembly and characterization of optical transmitter is also carried out and performance is analyzed in terms of different parameters such as Extinction ratio and Signal-to-Noise Ratio (SNR) etc.
