Novel EA-DFB Mode-Switching Transmitter Supporting Continuous Phase Frequency Shift Keying and Intensity Modulation for All-Photonics Network
A novel transmitter that offers both short-reach IM-DD transmission and higher optical budget coherent transmission is proposed for cost-effective user terminals. 25 Gb/s signal detection experiments confirm enhanced optical budget of 13 dB with high sensitivity of -37.7 dBm by modulation format switching.
