Modified Add-Drop Microring Resonator for Temperature Sensing

Abstract

A micro resonating sensor is proposed for simultaneous measurement of temperature and carrier density using modified Add-drop resonator called PANDA resonator from silicon-on-insulator (SOI) material waveguide. The proposed sensor works by observing the concentration of free-carrier in silicon around room temperature yielding the sensitivity of 1×10 23 m −3 C −1 with limit of detection of 10 −5 C. It is found that the output intensity decreases due to the photon and thermal absorptions. It is found that the performance of the PANDA sensor is affected by the power at the first coupling region and increase in propagating lengths of PANDA sensor causes a nonlinear effect in carrier density production.

“…In Figure , the presented device configuration is known as a Panda ring resonator , from which there are many research works reported. The optical outputs in the proposed device are presented in the forms of whispering gallery modes (WGMs) , from which the microconjugate mirror outputs can be constructed by adjusting the two side ring parameters.…”

“…To achieve the single device for a single eye 3D imaging, the double conjugate mirrors are introduced to be vertically constructed, where the the double Panda ring parameters are required to modify and adjust using the simulation technique, where in this work the commercial MATLAB and Opti‐wave are used.

Double critical coupled ring resonator-based add–drop filters

“…Integrated ring resonators have found a number of usages in integrated optics due to their compact size, low cost of fabrication and their ability to integrate with on chip circuits. Today, micro-size resonators are practical devices for switching [2][3][4], multiplexing, demultiplexing [5] and wavelength filtering [6,7], modulation applications [8], wide band antenna [9,10], modulator and logic gate in optical signal processing [11,12], and sensitive sensors and biosensors [13][14][15]. One of the primary applications of ring resonators is their application as an add-drop notch type filter in optical networks.…”

Novel Design of 3D Imaging Pixel On-chip Using A Micro-conjugate Mirror System

“…By using the Panda ring resonator, the whispering gallery modes outputs can be controlled and generated by the two nonlinear side rings easier than the integrated microring resonators. This device has also shown the interesting behaviors when the different wave forms are input into the system, thus, when the Gaussian, soliton and photon are input into the device [7][8][9], the output results obtained have shown the different aspects that are suitable for different usages [10][11][12][13][14][15][16][17]. One of the interesting aspects is that when the output is obtained in the form of whispering gallery modes (WGMs) [18], where principally they are the tunneling photons and formed at the center Panda ring device.…”
