Abstract

We demonstrate a low relative intensity noise (RIN) (<-125dBc/Hz from 1 MHz to 10MHz), continuous wave (CW) supercontinuum (SC) generation in standard telecom fiber using a low intensity noise 1064nm Ytterbium (Yb) doped fiber amplifier as pump source. The generated SC has >8dB of RIN improvement (over a bandwidth of 300nm from 1400nm to 1700nm) when compared to the RIN of SC generated by a conventional fiber Bragg grating (FBG) cavity based Yb fiber pump laser. Integrated root mean square (RMS) RIN of 0.16 (from 1MHz to 10MHz) was better than the low noise CW supercontinua reported so far. © 2024 SPIE.
