Journal ArticleDOI
Highly dispersive photonic band-gap prism
TL;DR: The highly nonlinear dispersion of PBG materials near Brillouin zone edges is recognized and utilize the dispersion to achieve strong prism action in the millimeter-wave spectral regime.
Journal ArticleDOI
Traveling-wave photodetectors for high-power, large-bandwidth applications
TL;DR: In this paper, the authors explored the power dissipation limit of traveling-wave photodetectors (TWPDs) and developed a small-signal steady-state model that includes the effects of electrical propagation losses along the detector.
Proceedings ArticleDOI
Small and large signal modulation of 850 nm oxide-confined verticai-cavity surface-emitting lasers
Kevin L. Lear,Vincent M. Hietala,Hong Q. Hou,J.J. Banas,B. E. Hammons,John C. Zolper,S.P. Kilcoyne +6 more
TL;DR: In this paper, the authors demonstrated record modulation bandwidths for oxide-confined vertical-cavity surface-emitting lasers (VCSELs) based on strained InGaAs/GaAs quantum wells.
Patent
Optical elements comprising photonic crystals and applications thereof
TL;DR: In this paper, the use of photonic crystals to form optical elements which function in optical apparatus in frequency ranges outside photonic band-gaps is described, and a variety of optical apparatus including spectrometers, radiation sources, and lasers are enabled by such optical elements.
Patent
Coherent optical monolithic phased-array antenna steering system
TL;DR: An optical-based RF beam steering system for phased-array antennas comprising a photonic integrated circuit (PIC) was proposed in this article, which is based on optical heterodyning employed to produce microwave phase shifting by a monolithic PIC constructed entirely of passive components.
