A reflowing photoresist and oxidation smoothing process is used to fabricate ultra-high-Q silicon microring resonators based on multimode rib waveguides. Over a wide range of wavelengths near 1550 nm, the average Q-factor of a ring with 1.2-μm-wide waveguides reaches up to 1.17 × 106, with a waveguide loss of approximately 0.28 dB/cm. For a resonat...

The massive data transfer rates of nowadays mobile communication technologies demand devices not only with outstanding electric performances but with example stability in a wide range of conditions. Surface acoustic wave (SAW) devices provide a high Q-factor and properties inherent to the employed materials: thermal and chemical stability or low pr...

Brillouin microlasers based on microresonators with whispering gallery modes (WGMs) are in high demand for different applications including sensing and biosensing. We fabricated a microsphere resonator with WGMs from a synthesized high-quality tellurite glass with record high Q-factors for tellurite microresonators (Q ≥ 2.5 × 107), a high Brillouin...

In this paper, a compact antenna suitable for integration in Internet-of-Things (IoT) terminals and whose performance approach the lower Q-factor theoretical bound is presented. The proposed antenna structure is a parasitic element array based on two Inverted-F Antenna (IFA) radiators sharing the same ground plane. The antenna exhibits a directive ...

Nowadays, Free Space Optical (FSO) communication has attained great importance because of high features such as large data rate, low power, and huge bandwidth. However, FSO technology suffers from several atmospheric effects such as rain, snow, fog, etc. To overcome these issues, an innovative Selective Active Relay (SAR) protocol is proposed in th...

The transmission of the high data rate and information over the optical fiber is restricted by various dispersion phenomenon which further results into intersymbol interference (ISI). This article proposes two different methodologies for optical fiber deformation aiding vibration monitoring one using the pin diode as a photo-detector device and ano...
