Developing Infrared Scene Projectors (IRSPs) requires consistent performance from the Close Support Electronics (CSE) used to drive the IRSP systems. This paper highlights the small-batch production and rotational testing of these CSEs, which provides a measure of consistency and quality assurance across multiple systems.

Honeywell is using Brillouin lasing in chip-scale SiO2/Si$_{3}N_{4}$ waveguide resonators to create a robust ring laser gyroscope. Limitations on gyro performance are cascading of Brillouin lasing to higher SBS orders and scattering loss of the Brillouin light in the resonator. We describe advances addressing each of these issues.

The theory of Transformation electromagnetics/Transformation Optics (TREM/TO) has emerged recently as a useful technique to design unique electromagnetic devices. One such device is a beam-shifter implemented with a non-homogenous dielectric layer. The invariant form of Maxwell’s equations under particular coordinate transformations is a foundational aspect of this theory, and the development of these beam-shifters. Using this approach, a novel application of multiple up-and down-beam-shifters is proposed and presented here to guide a normalized magnetic field from a half-wave dipole around an irremovable perfect electric conductor (PEC) at 20GHz. This beam-shifter is developed using theory and successfully validated with the full-wave finite element software COMSOL.

We experimentally demonstrate a broadly-tunable transceiver for radar and electronic warfare on a silicon photonic chip. The device exploits an innovative and simple lasers’ noise referencing architecture and achieves reconfigurable operation in the range 0.5-35GHz, an unprecedented image rejection ratio >80dB, and robust antenna-remoting capability.

Nitrogen-vacancy centers in diamond are emitters that function as sensors of electric and magnetic fields, temperature, and strain. Diamond’s high refractive index limits emitted light, reducing NV-based sensor performance. We demonstrate an easily-fabricable adjoint-optimized extractor that improves output from NV centers by 50-fold.

We incorporate new four-layer superlattices into cascaded mid-infrared superlattices for improved quantum efficiency, and thinning/roughening of the substrate (emission side) for improved light extraction. Each improves radiance of InAs/GaSb, untextured mid-infrared LEDs by ~3x; wallplug efficiency is improved >10x.

The root-of-trust in mission-critical systems originates with hardware. Evaluating each component for trust prior to installation is essential for modern electronic systems. We propose laser and emission-based microscopy to non-destructively assess integrated circuits with high confidence. We demonstrate this approach on a 28 nm device.

Changes in brainwave activity have been associated with hypoxia, but the literature is inconsistent. Twenty-five participants were subjected to normobaric hypoxia while undergoing a variety of cognitive tasks. The detected differences in brain activity between normal and hypoxic conditions are presented.
