概要

In last few decades, semiconductor industries have been grown exponentially due to continuous reduction in feature size. Although Moore’s law has continuously dominated the VLSI industry during last five decades, this law is reaching to its limit as the increasing number of transistors causing more power consumption, which in turn dissipates more heating and loss of information in non-reversible circuits. As a result, the current VLSI technology cannot be used further to reduce the size of the chip while controlling the heat dissipation. Several emerging technologies such as reversible computing, quantum computing and quantum photonics, etc. have been tried for circuit design to tackle this heat dissipation problem. Among all these technologies, silicon-based optical computing (a.k.a., Si-photonics) has been experimentally demonstrated as one of the potential technologies for next generation computing. Si-photonics is the combination of electronics and photonic circuits on a single chip that takes the advantages of both the technologies, viz., electronics and photonics. This is also most compatible with CMOS technology and has low fabrication cost with better performance compared to other technologies based on InP and TriPleX. In recent years, the design of all-optical circuits has received a great attention among CAD researchers due to high-speed and low-power characteristics and its compatibility with CMOS technology. The higher bandwidth of optical interconnection increases the data transfer rate among chips and further the integration of optical and electronic components on a chip can reduce the area and cost. Some basic combinational logic circuits like adders, subtractors, multiplexers have been designed with the help of optical components like semiconductor optical amplifier (SOA) based Mach-Zender interferometers (MZIs), ring-resonators, disc resonators, etc. However, in order to design bigger photonic integrated circuits (PICs), a design flow need to be followed as in electronics. The main challenges in design automation of PICs is minimization of number of optical gates and components, waveguide bends and area while using optical components to realize a circuit. Several logic synthesis techniques have been proposed by different researchers to implement PICs for a given input Boolean logic function. In this talk, we will discuss about basic optical components used in PICs and some state-of-the-art logic synthesis techniques for PICs published in literature.
