ThF1.1 - SCALING TOWARDS MONOLAYER PHOTONIC CRYSTAL LASERS
Abstract
Abstract
Energy efficiency is one of the grand challenges toward low energy-per-bit integrated photonics. We discuss progresses related to lasing gain medium scaling from conventional quantum well to quantum dot and monolayer 2D materials. We also discuss the lasing cavity scaling on various photonic crystal cavities.
WE1.3 - INTEGRATED BIORESORBABLE OPTICAL SENSOR SYSTEMS FOR BIOMEDICAL PRESSURE AND TEMPERATURE MONITORING
Abstract
Abstract
An integrated optical sensor is designed and fabricated for implantable applications in monitoring the pressure and temperature within intracranial, intraocular space. The sensing mechanisms utilize Fabry-Perot interferometry and photonic crystal resonance. The containing semiconductor material and integrated polymer fiber are selected to be all bioresorbable.

Abstract
Abstract
We report optically pumped 1 μm low threshold GaAs photonic crystal surface emitting lasers. The GaAs photonic crystal is etched on 3-period InGaAs/AlGaAs MQW heterostructure. A laser peak is achieved at 1,006 nm with a linewidth of 0.6 nm at 5 kW/cm2 threshold power density.
