چکیده
To satisfy the demand for inter chip interconnects bandwidth, current research projects are based on use of wave guided optical interconnects. The circuit is implemented to compensate high external capacitive loads. A maximum of 12 channels LASER diode each 10 GB/s is designed to reduce power consumption. The layout area, adjustable modulation current and bias current are achieved. Design can be used in high speed optical chips. The VCSEL’s and power diodes are also used to provide optimized high speed and performance of optoelectronic devices. For high speed, photonic ring modulator is designed at 25 GB/s. In these VCSEL drivers i.e. common source (CS), CS with source degradation and source follower is presented. Various CAD tools are used for implementation of CMOS based optical circuits. This paper is a review of design of different VCSEL’s and LASER driver circuits which are implemented on 180nm, 90nm and 65nm CMOS technology. The performance of various circuits is evaluated and compared in terms of power, power consumption, speed and maximal eye opening etc. Keywords-Optical Interconnects, Vertical Cavity Surface Emitting Laser, Photo Detectors

The bandwidth of global on-chip interconnects in modern CMOS processes is limited by their high resistance and capacitance [1]. Repeaters that are used to speed up these interconnects consume a considerable amount of power [2] and area. Recently published techniques [1-4] increase the achievable data rate at the cost of high static power consumption, leading to relatively high energy per bit fo...
