Integrated waveguide bandpass filters using thick-film technology

, 2004
By integrating planar circuits, such as a microstrip line, and the rectangular waveguide with inductive posts onto the same substrate, the low-loss bandpass filter can be realized without resort to tuning or mechanical mounting.

Transcending the Space‐Bandwidth and Lighting Trade‐Offs: A Programmable Self‐Mixing Interferometry Imager for Cross‐Scale Surface Inspection

Laser &Photonics Reviews, EarlyView.
This work reports a laser diode‐based self‐mixing interferometry imager featuring illumination‐invariance imaging, a 500 kHz pixel rate, and an 8.77 µm lateral resolution. It also features a programmable field‐of‐view and leading space‐bandwidth product that surpasses existing technologies by an order of magnitude, enabling cross‐scale workflow ...

Chip Scale Emission of Blue Light at Elevated Temperatures in Optical Waveguides Integrated With Rubidium Vapor

Laser &Photonics Reviews, EarlyView.
An integrated atom‐clad waveguide enables chip‐scale blue light generation (420 nm) via a two‐photon ladder transition in rubidium vapor at temperatures up to 240°C. The observed bell‐shaped intensity profile reveals a competitive interplay between local photon generation and macroscopic vapor reabsorption.

Multispectral Mid‐Infrared Imaging With Incoherent Light via Adiabatic Upconversion

Laser &Photonics Reviews, EarlyView.
We demonstrate room‐temperature broadband MIR imaging based on adiabatic frequency upconversion, driven by a Q‐switched pump laser and incoherent illumination. The small‐foot‐print system upconverts the spectral range to the visible domain, without scanning, thermal control and with spatial resolution below 20μm$20\mathrm{\mu}\mathrm{m}$.
