Wide-Passband $\mathrm{C}+\mathrm{L}$-Band Wavelength Selective Switch by Alternating Wave-Band Arrangement on LCOS

We propose a novel optical system that employs alternating wave-band arrangement on LCOS for multi-band operation. We demonstrated a 2-in-1 1×10 wavelength selective switch (WSS) with the operational range of C+L-band by using multiple PLC frontends.
