Efficient Low‐Voltage Phase Shifter with Inkjet‐Printed Liquid Crystal on a Silicon on Insulator Platform

open access: yesAdvanced Optical Materials, EarlyView.
Demonstration of an electro‐optic phase shifter fabricated by inkjet printing liquid crystal on an integrated silicon photonics chip surface. On a completed silicon photonics wafer (including modulators, detectors, and metallization), the back‐end‐of‐line stack is opened up to inkjet‐print liquid crystal. A phase shift of 6 for 2.7 V is obtained within

High‐Chroma, High‐Contrast Tunable Color Coatings Using Sb2S3 in a Metal‐Dielectric Stack

open access: yesAdvanced Photonics Research, EarlyView.
A novel tunable color coating design is presented, using the phase‐change material Sb2S3 in a Fabry–Perot cavity. The resulting coatings yield bright, attractive colors, and display a significant color change when annealed using a hotplate or a laser. This demonstrates that Sb2S3 is a promising candidate for use in tunable color coatings.

Inflatable Kirigami Crawlers

open access: yesAdvanced Robotics Research, EarlyView.
Inflatable kirigami crawlers are fabricated from heat‐sealable textiles and achieve motion through cyclic pneumatic actuation. Strategically placed kirigami cuts guide asymmetric deformation, doubling contraction compared to traditional pouches and forming scale‐like surfaces.
