Title: Innovations of Bilas Chowdhury in Optical Communications
Introduction
Bilas Chowdhury is a notable inventor based in Melbourne, Florida, recognized for his contributions to optical communications technology. With a total of three patents to his name, Chowdhury has made significant advancements in the field, particularly in the area of pulse amplitude modulation and spatial domain multiplexing.
Latest Patents
Chowdhury's latest patents focus on systems designed to achieve multiple bits per symbol in optical communications. One of his key inventions is a modified optical PAM communication system that utilizes multiple laser sources to generate each amplitude level. This system can operate independently or in conjunction with other modulation systems such as spatial domain multiplexing (SDM), mode division multiplexing (MDM), wavelength division multiplexing (WDM), and time division multiplexing (TDM). In one embodiment, a PAM-4 system can double the data rate, allowing for a 25 Gbps NRZ signal to produce a 50 Gbps PAM-4 signal. Furthermore, more advanced configurations using additional lasers can achieve PAM-8 or PAM-16, resulting in data rates of 75 and 100 Gbps, respectively. These innovations can be integrated with SDM systems to enhance data rates, effectively multiplying the number of SDM channels by the PAM efficiency.
