“…A schematic of the prototype ultra‐low noise (ULN) ECDL is shown in Figure a. It combines a high performance semiconductor gain chip (GC) and a polarization‐maintaining (PM) optical fiber with an integrated custom designed fiber Bragg grating (FBG), which forms one end of the ECDL. The GC consists of a multi‐quantum well (MQW) active region grown on an InP substrate.…”

An external-cavity diode laser for 1550-nm wavelength is reported with ultra-low noise, high power coupled to a fiber, and fast tunability. These characteristics enable the generation of an optical frequency comb in a silica micro-resonator with a single-soliton state. Neither an optical amplifier nor a modulator is used in the experiment. This demonstration greatly simplifies the soliton generation setup and represents a significant step forward to a fully integrated soliton comb system.

“…Many techniques have been studied to reduce the linewidth of lasers, and great developments have been achieved on narrowing the linewidth of lasers. The technique of distributed Bragg reflector and distributed feedback can reduce the linewidth of a semiconductor laser to less than 100 kHz [4], [5]. Especially in recent years, the planar-waveguide external-cavity laser technology is able to squeeze the linewidth of laser diodes to as narrow as about 3 kHz, which is approaching the performance of a typical fiber laser [6].…”

Strong Linewidth Reduction by Compact Brillouin/Erbium Fiber Laser

We demonstrate the strong linewidth reduction by a compact Brillouin/erbium fiber laser (BEFL), in which 4-m erbium-doped fiber (EDF) acts as both the Brillouin and linear gain media. Due to the assistance of the linear gain in the EDF with the acoustic damping and the cavity feedback in the resonator, the proposed BEFL transferred the 20-MHz Brillouin pump (BP) into the 950-Hz Brillouin Stokes laser emission, demonstrating that the laser linewidth is reduced by over 2 Â 10 4 times through this BEFL. The linewidth reduction is independent of the 980-nm pump power or the BP wavelength. The BEFL keeps strong linewidth reduction over the whole C-band. This effect of the BEFL provides a simple but effective way to obtain highly coherent light for many applications.Index Terms: Linewidth reduction, Brillouin/erbium fiber laser, stimulated Brillouin scattering.

A method of fabricating dual-wavelength fiber Bragg grating with a uniform phase mask is demonstrated. Theoretical analysis and numerical simulation using Matrix method are given. The moving exposing technique is adopted. Good control over the grating's reflectivity and the separation of the two Bragg wavelengths is enabled by adjusting the stretch, the length of the grating, and the exposure. A grating with two equal transmission peaks of 19.5 dB is obtained by using this method, and the separation of the two Bragg wavelengths is 0.78 nm.
