“…The polarized control is applied to the sensing probe add port. The total electron cloud phase shift of each sensing probe within the system is given by an equation (10), which is obtained by the polarized electron cloud phase shift of an equation (5). The result of each probe can be identified by the different traveling times.…”

“…There are different types of Sagnac interferometers that have been designed, developed, and employed for sensing applications [4][5][6][7][8]. The micro-scale system known as micro-electro-mechanical system (MEMS) technology is used to develop resonators for various applications [9][10][11][12], where the resonators such as panda ring, micro ring, and MZI have been applied. Recently, microring resonators have been widely used in both theoretical and experimental works [13][14][15][16], where the realistic applications have been confirmed.…”

A micro Sagnac interferometer is proposed for electron cloud distributed sensors formed by an integrated (micro-electro-mechanical systems) MEMS resonator structure. The Sagnac interferometer consists of four microring probes integrated into a Sagnac loop. Each of the microring probes is embedded with the silver bars to form the plasmonic wave oscillation. The polarized light of 1.50µm wavelength is input into the interferometer, which is polarized randomly into upstream and downstream directions. The polarization outputs can be controlled by the space-time input at the Sagnac port. Electrons are trapped and oscillated by the whispering gallery modes (WGMs), where the plasmonic antennas are established and applied for wireless fidelity (WiFi) and light fidelity (LiFi) sensing probes, respectively. Four antenna gains are 2.59dB, 0.93dB, 1.75dB, and 1.16dB, respectively. In manipulation, the sensing probe electron densities are changed by input source power variation. When the electron cloud is excited by the microscopic medium, where the change in electron density is obtained and reflected to the required parameters. Such a system is a novel device that can be applied for brain-device interfering with the dual-mode sensing probes. The obtained WGM sensors are 1.35µm -2 , 0.90µm -2 , 0.97µm -2 and, 0.81µm -2 , respectively. The WGMs behave as a four-point probe for the electron cloud distributed sensors, where the electron cloud sensitivities of 2.31prads -1 mm 3 (electrons) -1 , 2.27prads -1 mm 3 (electrons) -1 , 2.22prads -1 mm 3 (electrons) -1 , 2.38prads -1 mm 3 (electrons) -1 are obtained, respectively.

“…Owing to this issue, it is desirable to enhance the coupling between the racetrack MRR and the bus waveguide, which will theoretically increase the ER. The notch depth is related to both to the racetrack MRR roundtrip loss and the power coupling coefficient between the ring and bus waveguide [29]. In this work, the radius R d was set as 5 µm to increase ER.…”

In this work, we have proposed and designed a 1 × 1 optical switch based on the optical phase-change material, Ge2Sb2Se4Te1 (GSST), for GSST-assisted silicon racetrack microring. Its optical power can periodically be exchanged between the straight silicon waveguide and the GSST/Si hybrid racetrack waveguide due to the formed directional coupling structure. By changing GSST from the crystalline state to the amorphous state, the switch shifts from the ON state to the OFF state, and vice versa. With finite-difference time-domain method optimization, the proposed switch shows an extinction ratio of 18 dB at 1547.4 nm. The insert losses at the ON and OFF states are both less than 1 dB. The proposed switch unit has the potential to build an N × N switch matrix.
