Abstract	New designs for a 1×4 and a 1×8 CWDM multiplexers based on cascaded groups of series coupled ring resonators [1]–[3] are presented. Compared to other integrated optical alternatives such as MMI phasars, cascaded Mach-Zehnder interferometers and cascaded AWG, the proposed circuits offer superior performance in their very sharp roll-off factor that exceeds 0.75, their reduced crosstalk level that lies below −80 dB and their negligible insertion loss for the 1×4 design. For the 1×8 design, the worst case insertion loss is 4 dB. However, the performances obtained exhibit passband ripples in the order of 5 dB, and besides, they are not very tolerant to fabrication errors. Being designed for SOI technology, the proposed circuits are compact as the circuit areas are 130×130 $µm^{2}$ and 90×150 $µm^{2}$ for the 1×4 and 1×8 designs, respectively. They also have a high potential for MEMS tunability.
