Tenders are invited for Narrow Linewidth
785Nm Diode Lasers
The new design allows for narrower open-loop linewidth
(10 MHz over a 1 s integration time) and reduced jitter both at a single wavelength and while scanning.
Active optical clocks provide several new possibilities of applications: (i) more stable optical clock than any current atomic clocks; (ii) sub-natural linewidth
laser spectroscopy; (iii) long coherence time laser with linewidth
at mHz level; (iv) Ramsey laser combining stimulated emission process and Ramsey separated oscillatory fields method," commented Professor Yiqiu Wang.
Lasers should have an extra-cavity output power of at least 100 mW and linewidth
of not more than 200 kHz @ 1 us free running.
NeoPhotonics is a supplier to Huawei of Access products designed for its Broadband FTTx systems and of advanced WDM Transport products, such as integrated coherent receivers and narrow linewidth
tunable lasers designed for its 40G and 100G Coherent transport systems.
They examine linewidth
broadening, widely tunable monolithic laser diodes, practical issues, related DWDM sources, communications applications and requirements, and other applications.
CD-SEM images of linewidth
test patterns were analyzed to determine the lines' widths and the angles of their edges.
One of these properties is that the linewidth
enhancement factor of a QCL is close to zero, compared to two to five for a conventional laser.
The battle between metal mesh suppliers will be fought on narrowing the linewidth
and improving throughput and yield (biggest cost unknown/driver).
This is the first test of the library-based shape-sensitive linewidth
measurement method on nested lines.
The NMR detection coil mounted is made of susceptibility matched material capable of shimming solution linewidth
In addition, NeoPhotonics is showcasing its broad line of active and passive optical components, modules and subsystems for optical network segments, including: Integrated Coherent Receivers (ICR) and Narrow Linewidth
Tunable Lasers (NLW-TL) for coherent 40 Gbps and 100Gbps systems; 40Gbps and 100Gbps CFP modules, SFP, SFP+ and XFP transceivers; GPON, GEPON, 10GPON and NGPON OLTs; Athermal Arrayed Waveguide Gratings (AWG); and Multicast Switches, at the OFC/NFOEC Conference and Exposition at the Los Angeles Convention Center, Booth 2200, March 6 - 8, 2012.
