Tunable dispersion compensator and method for tunable dispersion compensation |
摘要 |
A tunable dispersion compensator and a tunable dispersion compensation method having an excellent dispersion compensation characteristic are provided. A tunable dispersion compensator 201 is constructed of first to fourth ring resonators 202 <SUB>1 </SUB>to 202 <SUB>4 </SUB>connected in series along a common linear waveguide 203 . The linear waveguide 203 is provided with first to fifth mode filters 204 <SUB>1 </SUB>to 204 <SUB>5 </SUB>in such a way as to sandwich the ring resonators 202 <SUB>1 </SUB>to 202 <SUB>4 </SUB>respectively. These mode filters 204 <SUB>1 </SUB>to 204 <SUB>5 </SUB>eliminate high-order mode noise components which transmit through the linear waveguide 203 . The mode filters 204 <SUB>1 </SUB>to 204 <SUB>5 </SUB>are constructed with the width of a central waveguide reduced or in a curved shape.
