We demonstrate clock recovery at 35 Gb/s from the first mode-locked laser integrated on-chip with input and output SOAs. Tuning one DBR mirror can change the output pulsewidth between 6.7 and 9.3 ps. 1. Introduction Optical clock recovery (OCR) at high data rates is desirable for regeneration of data in fiber optic networks [1,2]. Mode-locked lasers (MLLs)… (More)
Question: In the microwave portion of the electromagnetic spectrum, does it make a difference in terms of how much energy is scattered by snow crystals, whether or not they have a particular orientation in regards to each other? Put in another way, in calculating the amount of energy that is transferred from the ground, through the snowpack, can it be… (More)
We demonstrate a regenerative optical router node showing 2R and 3R regeneration on 40Gb/s labeled optical packets. Successfully achieved >5dB increase in received power sensitivity and obtained >99% edge-to-edge Ethernet frame recovery.
Surrogate technologies for bed-load transport monitoring are being evaluated toward eventually supplanting traditional data-collection methods that require routine collection of physical samples and subsequent fi eld or laboratory analyses. Commercially available and prototype technologies based on active-and passive-hydroacoustic principles are the foci of… (More)
