Abstract

Silicon Photonics used coherent light modification, transmission, and detection. (SP). In the decade since Silicon World, inactive optical devices, modulators, signal processors, sensors, and others have advanced technologically. These happened. SP provides low-cost photonic solutions for short-, medium-, and long-haul telecommunications and chip-to-chip interconnects. SP-based transceivers and photonic integrated circuits have advanced during the past decade. (PIC). CMOS manufacture allows complex silicon PICs to be employed in massive data centers, high-bandwidth short-range communications, and dependable long-haul systems. This thesis includes junction-less silicon photonic modulators, coupling modulators, and PIN diode switches. This thesis describes a technologically programmable, compact, high-speed, low-power photonic switch. Plasma dispersion switches MMIs optically. Quantitative analysis and switch design recommendations are in the thesis. An active MMI coupler-based silicon ring-based coupling modulator is suggested and investigated. PIN diode-based electrically adjustable active MMI couplers can handle high-modulator footprint conventional coupling coefficient modulators. This thesis rates the suggested modulator. Eventually, a family of silicon photonic junction-less devices employing electrostatic doping (ED) solves random dopant fluctuations and accidental dopant activation in junction-based micro/nano-scale active silicon photonic devices. Technology improves. Electrostatic loading science is also taught. Three ED-assisted modulators are proposed and studied. First, an ED-aided phase shifter-loaded tiny Mach-Zehnder modulator (MZM) for intra-chip and short-haul communication is suggested and investigated. High-linear, low-power, junctionless modulator. Second, a short-haul EAM is shown.
