New methods for subcarrier type optical reception applying new single sideband optical-microwave mixers

For the reception of subcarrier modulated optical signals a new method has been developed using combined optical-microwave mixers. Two arrangements are presented applying a new single sideband optical-microwave mixing process, resulting in a simpler arrangement and in an improved performance. Using this method an image frequency suppression of 20-25 dB is achieved.<<ETX>>
