Germanium‐Based Mid‐Infrared Integrated Photonics

open access: yesLaser &Photonics Reviews, EarlyView.
The mid‐infrared (mid‐IR) spectral range is a part of the electromagnetic spectrum in which most of the molecules have vibrational and rotational resonances. Photonics integration in this wavelength range have thus seen a burst of interest in the recent years, mainly driven by applications related with the detection of chemical and biological ...

Fabrication of Polymeric Multimode Waveguides for Application in the Local Area Network and Optical Interconnects. [PDF]

open access: yes, 2000
We report the fabrication of multimode polymeric waveguides using spin coating, photolithography, and reactive ion etching. Different layer structures have been used, e.g., a UV curable resin is used as a core layer and PMMA as a lower and upper cladding.

Ultrahigh‐Order Harmonic Mode‐Locked Optoelectronic Oscillator

open access: yesLaser &Photonics Reviews, EarlyView.
This article demonstrates a record‐breaking microwave frequency comb generator using an ultrahigh‐harmonic‐order mode‐locked optoelectronic oscillator. By integrating dual recirculating loops into a low‐coherence system, the researchers achieved a harmonic order of 956 with superior noise suppression.
