Spectral Peaked Optical Frequency Comb for Highly Sensitive Spectroscopy

Advanced Photonics Research, Volume 7, Issue 1, January 2026.
Optical frequency combs represent a breakthrough in metrology, and comb mode selection and power scaling are important issues for highly sensitive spectroscopy. This article reviews the development of a spectrally peaked optical frequency comb using the novel phenomenon of spectral peaking for highly sensitive spectroscopy.

An On‐Chip Elliptic Bandpass Filter With High Selectivity and High Stopband Attenuation Near the Passband Based on Stacked Series‐Parallel Topology

IET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.
A high selectivity integrated passive device (IPD) on‐chip bandpass filter is presented. The stacked series‐parallel topology is employed to generate two transmission zeros and a transmission pole to maintain high selectivity and high stopband attenuation near the passband.
