Abstract

We report an injection locked flexible wavelength de-multiplexer (de-mux) that shows 24-h frequency stability of 1 kHz for optical comb-based elastic optical networking applications. We demonstrate 50 GHz, 87.5 GHz equal spacing and 6.25G-25G-50 GHz, 75G-50G-100 GHz unequal spacing for the de-multiplexer outputs. We also implement an unequally spaced (75G-50G-100 GHz), mixed symbol rate (12.5 GBaud and 40 GBaud) and modulation format (polarization division multiplexed quadrature phase shift keying and on-off keying) wavelength division multiplexed transmission system using the de-multiplexer outputs. The results show 0.6 dB receiver sensitivity penalty, at 7% hard decision forward error correction coding limit, of the 100 km transmitted de-mux outputs when compared to comb source seeding laser back-to-back.

摘要

我们报道了一种注入锁定的灵活波长解复用器（解复用器），它在基于光梳的弹性光网络应用中展现出1kHz的24小时频率稳定性。我们展示了该解复用器输出的50GHz、87.5GHz等间距以及6.25G - 25G - 50GHz、75G - 50G - 100GHz不等间距。我们还使用该解复用器的输出实现了一个不等间距（75G - 50G - 100GHz）、混合符号率（12.5GBaud和40GBaud）以及调制格式（偏振复用正交相移键控和开关键控）的波分复用传输系统。结果表明，与梳状源种子激光器背靠背相比，在7%硬判决前向纠错编码限制下，100km传输的解复用器输出的接收灵敏度损失为0.6dB。
