Utilizing tunable silicon ring resonator filter as an external resonator, the wavelength tunable laser has demonstrated excellent wavelength tunability and less than 100 kHz narrow spectral linewidth, thus is promising to be applied to digital coherent optical communication systems. In order to apply to higher-order modulation formats, further narrower spectral linewidth is desired. However, with the previous filter structure, because of the trade-off relationship between spectral linewidth and gain difference of longitudinal modes, it is difficult to obtain both narrower spectral linewidth and stable single mode oscillation. In this paper, we demonstrate that by utilizing a highly asymmetric Mach-Zehnder interferometer which has a very long optical delay line, the newly designed filter can have both long cavity length and large longitudinal mode gain difference. From our experimental results, 49 dB high side mode suppression ratio(SMSR) and about 12 kHz narrow spectral linewidth were confirmed. |
