Moth eyes inspire antireflective surfaces for military applications
The corneal surface of many insects is structured with a subwavelength grating of protrusions believed to provide wide bandwidth antireflective properties. (PhysOrg.com) — If you look closely at the surface of a moth’s cornea, you see that it is comprised of tiny protruding bumps. These bumps exist to keep moths safe from predators by preventing … Continue reading
Photonics in mmwave Radios
We report on advanced millimeter-wave (mm-wave) photonic components for broadband radio transmission. We have developed self-pulsating 60-GHz range quantum-dash Fabry-Perot mode-locked laser diodes (MLLD) for passive, i.e., unlocked, photonic mm-wave generation with comparably low-phase noise level of -76 dBc/Hz @ 100-kHz offset from a 58.8-GHz carrier. We further report on high-frequency 1.55-μm waveguide photodiodes (PD) … Continue reading
