Understanding of efficient optical circuit using silicon waveguide at third communication window

The present study explores the design and performance evaluation of an efficient optical circuit leveraging silicon waveguide technology at third communication window. The proposed circuit architecture comprises a light-emitting diode (LED) as the transmitter, an optical fiber acting as the waveguide, and a photodiode serving as the receiver. The key components of an optical circuit exhibit exceptional efficiencies, with the LED achieving 99.5%, the silicon-based waveguide boasting 98.8%, and silicon-germanium based photodiode registering 99.6%. The LED is constructed using GaAs-based P and N layers, operating at a wavelength of 1550 nm (third communication window), while the waveguide is crafted from silicon-based optical fiber, and the Germanium (intrinsic layer) based photodiode consists of P-i-N structure. Through meticulous optimization and integration of these components, the proposed optical circuit achieves an outstanding overall efficiency of 97.9%. This high efficiency underscores the viability and effectiveness of the device for optical communication systems. The seamless synergy between the transmitter, waveguide, and receiver components ensures minimal signal loss and maximum signal integrity, making the proposed circuit well-suited for a wide range of optical communication applications. This research contributes to advancing the field of optical communication by offering a comprehensive understanding of efficient optical circuitry through silicon based waveguide technology at the third communication window.
