Modal Theory of Phase‐Modulated and Frequency‐Shifting Ring Cavities

open access: yesAdvanced Photonics Research, EarlyView.
We present a theoretical and experimental characterization of the optical modes of dispersionless ring cavities with phase modulators or frequency shifters. Their response to arbitrary modulation acts as a filter for phase‐modulated modes that determine the optical output of passive resonators and lasers. This provides a general framework for analyzing

Parasitism performance and fitness of Cotesia vestalis (Hymenoptera: Braconidae) infected with Nosema sp. (Microsporidia: Nosematidae): implications in integrated pest management strategy. [PDF]

open access: yesPLoS ONE, 2014
The diamondback moth (DBM) Plutella xylostella (L.) has traditionally been managed using synthetic insecticides. However, the increasing resistance of DBM to insecticides offers an impetus to practice integrated pest management (IPM) strategies by ...

Performance Evaluation of Produced Water Quality from a Nearshore Oil Treatment Facility

open access: yesJournal of Applied Sciences and Environmental Management, 2013
Produced water, which is a mixture of organic and inorganic compounds, is a major waste stream generated in oil and gas industries. Its negative impacts on the receiving water bodies have become a worrisome environmental issue. The effluent quality of a

Time-domain stability of parametric synchronization in a spin-torque nano-oscillator based on a magnetic tunnel junction

open access: yes, 2017
We report on a time-domain study of parametric synchronization in a magnetic tunnel junction based spin torque nano-oscillator (STNO). Time-domain measurements of the instantaneous frequency ($f_{i}$) of a parametrically synchronized STNO show random ...
