Design and Characterization of Low‐Threshold InP Nanowire Photonic Crystal Surface‐Emitting Lasers

Advanced Photonics Research, EarlyView.
The lasing performance of nanowire (NW) photonic crystal surface‐emitting lasers (PCSELs) is highly sensitive to changes in the photonic crystal lattice constant and the NW diameter. This study systematically investigates the threshold power and the threshold gain for different PCSEL geometries.

High‐Speed, Continuous, Large‐Angle Nonmechanical Beam‐Steering with Liquid Crystal Etalons

Advanced Photonics Research, EarlyView.
Liquid crystal (LC) is a strong candidate material for nonmechanical beam‐steering devices. This study proposes a new approach using three components: a superluminescent diode (SLD), an LC etalon, and a grating. Broad‐spectrum light from the SLD is passed through the LC etalon, generating wavelength‐swept light.

A Low‐Cost Curvature Detection Method for an Untethered Biped Pipeline Climbing Robot with Energy‐Efficient Strategy

Advanced Robotics Research, EarlyView.
A low‐cost pipeline curvature detection method has been proposed for an untethered biped pipeline surface climbing robot (BPCR) system with a five‐degree‐of freedom structure. The BPCR features adaptive vacuum suction cups equipped with multiple laser sensors on the suction modules to detect the curvature of various surfaces.
