Determination of the zero-position for an optical angle sensor

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2016
This paper proposes a new optical angle sensor, in which a mode-locked femtosecond laser referred to as the optical frequency comb is employed as the light source for the sensor.

Downsampling of optical frequency combs

Journal of the Optical Society of America B, 2018
We demonstrate repetition-rate downsampling of optical frequency combs by way of pulse gating. The reduced repetition rate enables increased pulse energy, facilitating efficient spectral broadening and f-2f interferometry. To explore the technique, we downsample a 250 MHz repetition-rate comb to 25 MHz and detect the carrier-envelope offset frequency ...

Structurally competent care for families facing the continuous traumatic stress of community violence and systemic racism

Journal of Traumatic Stress, EarlyView.
Abstract In racially and economically segregated communities, structural violence and chronic adversity perpetuate the risk for community violence and related trauma exposure. Despite widespread awareness of community violence, urban youth of color are among those least likely to have access to services that promote trauma recovery. When these youth do

Optical Frequency Comb Generation in Highly Nonlinear Fiber With Dual-Mode Square Microlasers

IEEE Photonics Journal, 2018
Optical frequency comb (OFC) generation based on four-wave mixing in highly nonlinear fiber (HNLF) is investigated using dual-transverse-mode square microlaser as a seed source.

Land Degradation Pathways of Open‐Pit and Underground Mining in Karst Regions: A Spatial Indicator Assessment

Land Degradation &Development, EarlyView.
ABSTRACT Mining in the karst regions of southwest China threatens ecosystem stability and accelerates land degradation. Regional evaluation rarely distinguishes between degradation pathways in open‐pit and underground operations, due to spatial heterogeneity and geomorphological confounding effects.

WDM optical interconnect enabled by optical frequency comb based on dual-drive modulator

, 2018
We report an optical frequency comb (OFC) generation by using a single dual-drive Mach-Zehnder modulator (DD-MZM). Over 21 comb modes with optical power above -5dBm and power flatness of 0.81 were generated within the -6 dB bandwidth of the OFC optical ...
