Abstract

A broadband wavelength photon squeezing system using a Panda-ring resonator embedded a gold grating is proposed. The selected laser source is input into the system via an input port, from which the nonlinear Kerr effect induced by the two nonlinear side rings and coupled into the center ring. Besides, the wavelength scattering is affected by the gold grating and the photon output wavelengths. By adjusting the suitable two side ring radii, where there is four type squeezing photons obtained. The obtained wavelengths are ranged from 1.30 to 170 µm with the center wavelength of 1.55 µm, where the maximum input power is 50 mW. From which the optimum spectrum range (FSR) of 22 nm is achieved. In applications, the up and downlink LiFi transmission can be formed using the whispering gallery mode node, in which the squeezed photons and the add port output can be used to form the communication. The signal modulation and demodulation can be applied via the device add and other ports, while the cable transmission is also available via the through the port connection. By using the Ti $${\text{O}}_{2}$$ reflector, the transmitted photons at the add port can also be controlled an attenuated, which can be used for single photon source and communication.
