Two dimensional nanomaterials like Molybdenum disulfide have been drawing a lot of interest due to their excellent nonlinear optical response. In this research we study thermal lens formation in MoS2 nanoflakes dispersion using mode mismatched pump probe configuration. Observation the and beam intensity patterns gave visual insights on time evolution photothermal formation. Effect concentration...

We describe the practical and fundamental limitations of the more prominent optical buffering approaches. The architectural implementation and needs of an optical packet switch are used as a foundation for the study. We also present initial results for a buffered, all-optical, 40 Gb/s packet switch. c © 2007 Elsevier B.V. All rights reserved.

To construct large-scale silicon electro-optical switches for optical interconnections, we developed a method using a limited number of power monitors inserted at certain positions to detect and determine the optimum operating points of all switch units to eliminate non-uniform effects arising from fabrication errors. We also introduced an optical phase bias to one phase-shifter arm of a Mach-Z...

Photonic all-optical switch is widely considered as one of the techniques to utilize the enormous optical bandwidth. This paper attempts to present a mathematical model for a loop buffer based switch and brings out the aspects of designing the all optical switch. The important aspects discussed are length of the optical loop and the design of EDFA. This paper also deals with the comparison of m...

This paper demonstrates the design of an Arrayed Waveguide Gratings (AWG) based optical switch. In the design both physical and network layer analysis is performed. The physical layer power and noise analysis is done to obtain Bit Error Rate (BER). This has been found that at the higher bit rates, BER is not affected with number of buffer modules. Network layer analysis is done to obtain perfor...

The paper describes research progress in technologies and architectures that give hope to deliver truly transparent switching of optical packets. The importance of all-optical packet switching/routing for convergent next generation transport network and in particularly, for QoS packet transfer in core of future generation wireless networks is pointed out. Generic photonic packet switch/router a...
