IS08 – Flat-band 8-Channel Optical MUX/DeMUX for Long Reach 400GbE Applications

Jeong S.-H.

We propose novel optical demultiplexer scheme for LR-8 applications, and theoretically verify flatband spectral response with the discrete 8-channel wavelengths. By the additional band rejection filter, non-continuous wavelength filtering response was achieved with spectral flatness and low crosstalk of < -15dB within an entire LR-8 targeted spectral range.
