Employing our 47 GHz bandwidth silicon photonic (SiP) traveling wave Mach-Zehnder modulator (TW-MZM), we demonstrate the transmission of 134 Gbaud PAM-4 (net 250 Gbps) at a BER below the 6.7% overhead hard-decision forward error correction (HD-FEC) t

We present the design and characterization of O-band and C-band silicon photonic (SiP) traveling wave Mach-Zehnder modulators (TW-MZM) allowing 220 Gbps/λ net rate operation. The designed modulators show over 45 GHz 3-dB E-O bandwidth with a single-

In a practical 4- $\lambda $ coarse wavelength division multiplexing (CWDM) intensity modulation direct detection (IM/DD) system, different wavelength channels achieve different transmission performances due to 1) inter-channel component differences

We demonstrate adiabatic couplers (ADCs) with design-intended splitting ratios (SRs) for the silicon-on-insulator (SOI) platform. The operational principle, numerical simulations, and experimental results on the designed ADC are presented. In the ope

We experimentally demonstrate a silicon photonic O-band polarization splitter and rotator. The wafer-level extinction ratio over 80 nm bandwidth has an average of 21.82 dB and 19.05 dB for the upper and lower ports, respectively.
