Abstract
Filter-free wavelength converters for separating and rejecting an optical input signal. A first input port couples a continuous wave (CW) light. A second input port couples an optical input signal. A multimode interference semiconductor optical amplifier (MMI-SOA) determines the output port with the input port and intensity-modulation of the CW light with the optical input signal. A first output port guides the converted signal, and a second output port guides the optical input signal.
Claims11
A XGM based filter-free wavelength converter, comprising:
- a first input port for coupling a CW light;
- a second input port for coupling an optical input signal;
- an MIMI-SOA for determining the output port with the input port and for intensity-modulation of the CW light with the optical input signal;
- a first output port for guiding the converted signal;
- and
- a second output port for guiding the optical input signal.
A XPM based filter-free wavelength converter, comprising:
- a first input port for coupling a CW light;
- a second input port for coupling an optical input signal;
- an optical divider for dividing the CW light into two paths of an interferometer;
- a first MMI-SOA for determining the output port with the input port and for phase modulation of the CW light with the optical input signal;
- a second MMI-SOA for determining the output port with the input port and for amplifying the CW light;
- an optical combiner for combining the CW light from the MMI-SOAs;
- a first output port for guiding the converted signal;
- and
- a second output port for guiding the optical input signal from the first MMI-SOA.
