Phase-Drift Limits and Adaptive Quadrature Readout in Programmable Photonic Processors
Gökhan Elmas, Igor A. Litvin, Janis Nötzel
Phase fluctuations between optical inputs limit programmable photonic processors because their output powers depend on coherent interference. We study the phase-drift penalty that…
Local Variance-Based Calibration of Programmable Photonic Interferometer Meshes
Gökhan Elmas, Igor A. Litvin, Janis Nötzel
Programmable photonic interferometer meshes enable reconfigurable linear optical transformations, but their performance depends critically on accurate calibration of Mach-Zehnder i…
Modeling and Analysis of Phase Instability in Photonic Processor
Gökhan Elmas, Igor Litvin, Paul Kohl +1
Achieving both reconfigurability and stable output signals is a critical challenge in the development of integrated photonic circuits for large-scale optical quantum information pr…
Robustness of WDM technique for the co-propagation of quantum with classical signals in an optical fiber
Sumit Chaudhary, Shahram Dehdashti, Igor Litvin +1
Many quantum communication systems operate based on weak light pulses which by design are assumed to operate in isolation from regular data traffic. With the widespread availabilit…
