We present the current state of art in micro-transfer printing for heterogeneously integrated silicon photonic circuits. The versatility technology is highlighted, as way ahead to make this a key enabler next-generation systems-on-chip.
The integration of dissimilar semiconductor materials holds immense potential for harnessing their complementary properties in novel applications. However, achieving such combinations through conventional heteroepitaxy or wafer bonding techniques presents significant challenges. In this research, we present a approach involving the direct InGaAs-based p-i-n membranes with GaN, facilitated by van der Waals forces and microtransfer printing technology. resulting n-InP/n-GaN heterojunction was...
We propose and demonstrate using the DIALux software with our proposed linear-regression machine-learning (LRML) algorithm for designing a practical indoor visible light positioning (VLP) system. Experimental results reveal that average position errors error distributions of model trained via simulation experimental data match each other. This implies training can be generated in if room dimensions LED luminary parameters are available. The scheme could relieve burden collection VLP systems.

Harnessing the properties of phonons on a chip, phononic integrated circuits are playing an increasingly important role in optoelectronic integration. To date, most such waveguides realized by etching piezoelectric layer and forming wire, which not only involves complicated fabrication processes but also limits integration with electronic photonic elements same chip. overcome these difficulties, here we propose demonstrate type overlay slot waveguide obtained patterning thin silicon cladding...
The most important blocks in the digital part of a RFID reader are MCU which controls all system work an efficient way and modulator is used to accomplish signal processing. As now commercial readers discrete component design researching on implementation single chip few, this paper point out that concentrates research baseband part. In new design, we make use open source IP core Leon3 developed by Aeroflex Gaisler control finish processing including CRC check, code decode, filtering so on....
