AO
Modulator
M040-8J-FxS
Description
A
fibre-coupled acousto-optic modulator and frequency shifter for use in
telecommunications. Optimised for low insertion loss at 1550nm, the use
of chalcogenide glass provides essentially no polarisation sensitive
loss or polarization mode dispersion. Very high extinction ratio and
rise-time make this device suitable for all-optical switching and
re-routing applications.
In
addition to the two fibre version, a three fibre model allows both zero
and first order output beams to be utilised. |
