Unraveling the Origin of Mysterious Luminescence peak at 3.45 eV in GaN Nanowires
Swagata Bhunia, Soumyadip Chatterjee, Ritam Sarkar +3
The demand for GaN Nanowires (NWs)-based optoelectronic devices has rapidly increased over the past few years due to its superior crystalline quality compare to their planar counte…
Ultrafast Green Single Photon Emission from an InGaN Quantum Dot-in-a-GaN Nanowire at Room Temperature
Swagata Bhunia, Ayan Majumder, Soumyadip Chatterjee +5
In recent years, there has been a growing demand for room-temperature visible single-photon emission from InGaN nanowire-quantum-dots (NWQDs) due to its potential in developing qua…
Optimization of Balanced Detector for Coherent Receiver on Generic InP Platform by PSO
Dhiman Nag, Weiming Yao, Jos J. G. M. van der Tol
Balanced photodetector (BPD) is an important component for high-speed coherent receiver. Optimization strategy of waveguide-based multi-quantum well (MQW) BPDs, operating at 1550 n…
Scaling nanowire-supported GaN quantum dots to the sub-10-nm limit, yielding complete suppression of the giant built-in potential
Swagata Bhunia, Ritam Sarkar, Dhiman Nag +3
The nanowire-supported quantum dot (NWQD) of GaN is an unconventional nanostructure, which is extremely promising for realization of UV photonics in general, and room-temperature s…
Engineering decomposition-resilience and de-coalescence of GaN nanowire ensembles
Swagata Bhunia, Ritam Sarkar, Dhiman Nag +4
The rapidly increasing interest in nanowires (NWs) of GaN and associated III-Nitrides for (opto-)electronic applications demands immediate addressal of the technological challenges…
