MODULATOR BIAS CONTROLLERS
Photonic Systems, Inc. offers modulator bias
controller (MBC) products that maintain a
specific point on the transfer function curve of
an electro-optic modulator.
The PSI-0204-11 chip-scale small signal bias controller is
a highly accurate small form factor device intended for
OEM applications. This modulator bias controller allows
you to select the bias point at the QUAD +/- or MIN/MAX
points on the transfer function of the modulator. The
PSI-0204-99 evaluation kit is also offered and strongly
suggested for first time users of the PSI-0204-11 to aid
with the design integration process.
The PSI-0204 is also offered in a bench-top laboratory
version with full control knob features and display
The PSI-2011-11 is a miniature modulator bias
controller circuit card that provides highly accurate
QUAD+ modulator transfer function point control.
The PSI-0404-11 Power Ratio modulator bias controller
maintains a user adjustable bias point by holding a fixed
power ratio of the optical input and output ports.
The PSI-0303 bench-top MBC model is a dither free digital
bias controller that works best with digital NRZ or RZ
PSI can also modify its bias controller products to meet
customer needs. Please contact PSI with you modulator bias
controller application requirements.
