Special Issue Information

Dear Colleagues,

It is my pleasure to invite you to contribute to this Special Issue of Micromachines, which will be dedicated to Novel Silicon-Based Optoelectronic Devices. Silicon photonics opens a new era for optical fiber communications, as well as the emerging optical interconnection, on-chip optical sensing, quantum information processing. Based on the established CMOS electronics fabrication process and methods, silicon photonics enables the standardized mass micro/nano manufacturing in photonics and optoelectronics industries. With the higher requirements of multi functionalities, low cost and ultracompact integration on photonics chip, discoveries in Si-based optoelectronic devices and their applications, as well as the micro/nano manufacturing process, are urgently desired. The aim of this Special Issue is to put together a collection of papers covering different applications to highlight the most recent scientific discoveries and trends in this continuously and rapidly evolving field.

Electro-optic modulator (EOM) is one of the key devices of high-speed optical fiber communication systems and ultra-wideband microwave photonic systems. Silicon–organic hybrid (SOH) integration platform combines the advantages of silicon photonics and organic materials, providing a high electro-optic effect and compact structure for photonic integrated devices. In this paper, we present an SOH-integrated EOM with comprehensive investigation of EOM structure design, silicon waveguide fabrication with Slot structure, on-chip poling of organic electro-optic material, and characterization of EO modulation response. The SOH-integrated EOM is measured with 3 dB bandwidth of over 50 GHz and half-wave voltage length product of 0.26 V·cm. Furthermore, we demonstrate a microwave photonics phase shifter by using the fabricated SOH-integrated dual parallel Mach–Zehnder modulator. The phase shift range of 410° is completed from 8 GHz to 26 GHz with a power consumption of less than 38 mW. Full article

In the last ten years, silicon photonics has made considerable strides in terms of device functionality, performance, and circuit integration for a variety of practical uses, including communication, sensing, and information processing. In this work, we theoretically demonstrate a complete family of all-optical logic gates (AOLGs), including XOR, AND, OR, NOT, NOR, NAND, and XNOR, through finite-difference-time-domain simulations using compact silicon-on-silica optical waveguides that operate at 1.55 μm. Three slots, grouped in the shape of the letter Z, make up the suggested waveguide. The function of the target logic gates is based on constructive and destructive interferences that result from the phase difference experienced by the launched input optical beams. These gates are evaluated against the contrast ratio (CR) by investigating the impact of key operating parameters on this metric. The obtained results indicate that the proposed waveguide can realize AOLGs at a higher speed of 120 Gb/s with better CRs compared to other reported designs. This suggests that AOLGs could be realized in an affordable manner and with improved outcomes to enable the satisfaction of the current and future requirements of lightwave circuits and systems that critically rely on AOLGs as core building elements.
