We demonstrate for the first time a phase stabilized Kerr comb without the use of external references or non-linear interferometry. Out-of-loop measurements confirm good coherence and stability across the comb, with measured optical frequency fractional instabilities of 5×10−11/√τ
We report the functionalization of high-Q silica microdisks with WSe2 and their optical characterization. Background-free cavity enhanced photoluminescence and photoluminescence saturation are observed at room temperature. We show precise measurements of the quantum yield of WSe2.
A novel TFET known as Double Source Tunnel FET (DS-TFET) is proposed in this paper, which provides higher ON current (ID-ON) with smaller turn-on voltage as compared to present Si based Tunnel FETs. The tunneling area is considerably enhanced which in turn increased the on-current ID-ON (∼29.2 μA/μm) for a smaller turn-on voltage (Vtu = 0.15 volt). The results of rigorous 2D simulation are presented...
This paper presents a ring loaded arrow shaped ground slot harmonic rejection antenna for 2.45 GHz wireless power transfer applications. By using open stub and H-slot in the feed-line, higher order harmonics have been suppressed.

This paper is based on merging of concepts involved in vertical and horizontal common sub-expression elimination...
In this paper, a highly adaptive swarm intelligence inspired optimally gamma corrected intensity coverage maximization approach has been proposed for quality enhancement of dark and low contrast remotely sensed images. Various image enhancement techniques have been proposed till date, but in case of dark images, most of them are suffering from saturation effects in higher intensity regions along with...
Fish conservation is a concern due to the impact of industrial fishing that causes overfishing. Fish farming has been an approach to fish conservation and systems are required to monitor ecosystems. This paper describes the design of a solar powered autonomous fish pond management system that can be used for fish conservation. The system consists of a floating node, equipped with sensors, that is...
FDSOI is one of the alternative device architectures chosen to extend CMOS scaling for high-k metal gate. FDSOI is ideal for applications needing a balanced trade-off among power, performance and cost, such as the Internet of Things (IoTs). One of the challenges in FDSOI integration is to obtain a low gate to source drain capacitance (overlap capacitance or DC capacitance). To enable this, low k spacer...
