Dr.Ashok Jhunjhunwala has made significant contributions to the area of Surface Acoustic Wave Theory and Applications in the early years of his research career. He has now expanded his interests also to the areas of Communication Networks, Fibre Optic Communications, and Optical Signal Processing. While doing his Ph.D. research and in subsequent years, Dr.Jhunjhunwala proposed a theory on Spectrum of Acoustic Waves excited by an IDT on a piezoelectric crystal. Later, working with his Ph.D. students, he has extended the analysis to planar bulk acoustic wave response.
Later, Dr.Jhunjhunwala branched out into the areas of Communication Networks and Fibre Optic Communications. One of his Ph.D. students investigated the Design of a High Speed Integrated Packet Switched Network, which represents the type of technology required in the future packetised voice-data communication network. In the area of fibre-optic communications, he has shown how voice communication can be easily added on the widely-deployed Ethernet Network. In the paper on Implementation Considerations in a Fibre Optic Bus Network, he has discussed the design considerations involved in fibre-optic bus networks.
In recent years, Dr.Jhunjhunwala has proposed a variant of the Symbolic Substitution Technique, which could significantly improve the efficiency of its application in Optical Signal Processing. Further, A Design Tool for Symbolic Substitution has been developed which enables design of complex Optical Signal Processing systems.
Over the last few years, Dr.Jhunjhunwala and his students have been looking at the use of enhanced Telecommunications and Signaling to significantly improve the throughput in a Railway Network. It is believed that on existing track and with training at current speed, it is possible to enhance the carrying capacity of Railways by a factor of about 5.
A significant piece of work, led by Dr. Ashok Jhunjhunwala, over the last decade, is an in-depth look at costs and affordability of various components of the Telecommunications and Internet Network, especially in the context of developing countries. Concluding that the access part of the network is the key bottleneck in rapid expansion in these countries, Dr.Jhunjhunwala has focussed his work on examining the appropriate interfaces between the Access Network and Backbone Network and different options to build a cost-effective network. His work includes an in-depth look at Wireless Access Networks and DSL (Digital Subscriber Loop) access networks as well as V5.2 interface and Internet bypass in the access network.
