DFB laser reference transmitter

A 2.5 Gbits/s laser transmitter can be used for proof-of-performance testing, general laboratory validation, and compliance testing at 1310 or 1550 nm. The benchto¥Model 420A produces fiber-coupled SONET/SDH-compliant output with eye patterns conforming to the CCITT G.957 standards over the range from OC-1 to OC-48 and STM-1 to STM-16.

A diagram shows NIST’s ion trap used for reversible “quantum squeezing” to amplify and measure ion motion. The ion (white ball) is confined 30 microns above the trap surface by voltages applied to the eight gold electrodes and the two red electrodes. Squeezing--that reduces the uncertainty of motion measurements--is achieved by applying a specific signal to the red electrodes. The ion is moved by applying another type of signal to one of the gold electrodes. Then the squeezing is reversed, and the blue electrodes generate magnetic fields used to decode the amplified motion measurements.
