Special Issue Information

Dear Colleagues,

The pursuit of optical control through advanced mechatronics systems represents a cutting-edge approach that seamlessly merges optics and mechatronics to achieve unparalleled precision in optical manipulation. This spans a diverse range of applications. For instance, in the domain of laser systems, it assumes a pivotal role facilitating indispensable functions such as laser beam steering and shaping, which are critical in fields like laser cutting, material processing, and medical applications. In the realm of imaging applications, particularly in microscopy, telescopes, and camera systems, exacting optical control is instrumental in ensuring utmost image clarity and precision. Within the astronomy community, telescopes and observatories reap substantial benefits from mechatronic control, notably in the context of Active Optics and Adaptive Optics, affording them the capability to track celestial objects with unparalleled precision. Furthermore, the versatility of those techniques extends to other domains, encompassing optical communications and the development of biomedical devices, where the fusion of optics and mechatronics engenders transformative progress.

The objective of this Special Issue is to delve into the interdisciplinary intersection of mechatronics and optics, shedding light on the synergistic potential of mechanical, electrical, and optical technologies in achieving precision in optical manipulation. We aim to collect a coherent ensemble of original articles and reviews emphasizing the following topics:

  • Innovative mechatronic systems for optical control
  • High-precision positioning and automation
  • Advanced laser systems with precise mechatronics
  • Mechatronic systems for imaging application
  • Novel control strategy design for Active Optics and Adaptive Optics

Abstract
We propose and demonstrate a novel on-chip optical sampling pulse interleaver based on time mode interleaving. The designed pulse interleaver was fabricated on a 220 nm silicon-on-insulator (SOI) platform, utilizing only one S-shaped delay waveguide. Interleaving is achieved by the relative time delay [...] Read more.
We propose and demonstrate a novel on-chip optical sampling pulse interleaver based on time mode interleaving. The designed pulse interleaver was fabricated on a 220 nm silicon-on-insulator (SOI) platform, utilizing only one S-shaped delay waveguide. Interleaving is achieved by the relative time delay between different optical modes in the waveguide, eliminating the need for any active tuning. The total length of the delay waveguide is 5620.5 µm, which is reduced by a factor of 46.3% compared with previously reported time-wavelength interleaver schemes. The experimental results indicate that the device can convert an optical pulse into a 40 GHz pulse sequence composed of four pulses with a root mean square (RMS) timing error of 0.9 ps, making it well suited for generating high-frequency sampling pulses for optical analog-to-digital converters.

High-precision displacement sensing has been widely used across both scientific research and industrial applications. The recent interests in developing micro-opto-electro-mechanical systems (MOEMS) have given rise to an excellent platform for miniaturized displacement sensors. Advancement in this field during past years is now yielding integrated high-precision sensors which show great potential in applications ranging from photoacoustic spectroscopy to high-precision positioning and automation. In this review, we briefly summarize different techniques for high-precision displacement sensing based on MOEMS and discuss the challenges for future improvement. Full article
