New design paradigm for highly efficient and low noise photodetector
Sagar Chowdhury, Rituraj, Srini Krishnamurthy +1
Achieving high quantum efficiency (QE) with low dark count is essential for highly sensitive photodetectors (PDs), including single photon avalanche detectors (SPADs). However, hig…

Highly sensitive and efficient 1550 nm photodetector for room temperature operation
Rituraj, Zhi Gang Yu, R. M. E. B. Kandegedara +2
Photonic quantum technologies such as effective quantum communication require room temperature (RT) operating single- or few- photon sensors with high external quantum efficiency (…
