“…Bandpass filtering is essential to guarantee stable dissipative soliton operation in such schemes, as it compensates the pulse broadening induced by the combined actions of dispersion and Kerr nonlinearity, thus stabilizing pulse duration over successive round-trips [2,6]. For this reason, most ANDi laser schemes include a narrow (∼1-10-nm bandwidth) bandpass filter [7][8][9][10][11][12][13][14][15][16]. The finite bandwidth of the gain medium (and other laser components) can play the role of a bandpass filter, thus avoiding the inclusion of a physical filter, however ytterbium-doped fiber gain is broadband; still, a growing number of papers report stable pulsed operation in this regime without the inclusion of a narrow filter [17][18][19][20][21][22].…”

In this work we study experimentally the temporal dynamics of an all-normal dispersion all-fiber ring laser far from stable mode locking. Temporal mapping relying on segmented memory capabilities of a fast oscilloscope is used for this purpose. A regime is found where radiation fills the cavity and is characterized by peaks that successively emerge, grow in amplitude while compressing temporally, before decaying abruptly, and localized low-intensity components mediating their interactions across the cycles. The highest-amplitude peaks ephemerally dominate intracavity radiation, before being superseded by other emerging peaks. As radiation covers the whole period and no permanent pulse ever emerges, the regime can be viewed as an intermediate stage between continuous-wave and mode locking operations. The interest of using segmented memory possibilities for proper characterization of this unconventional regime is highlighted.

“…Also, the second longitudinal mode must be placed on the longer wavelength side of the main mode at a distance equal to the desired position of the PPR and the oscillation mode of the PPR may be decided by the mode that is output as the result of interference between multiple modes similarly to the mode lock laser in the mode-locking regime. 29,30) The active-MMI LD consists of a single-mode waveguide structure on each side of a multimode section, and the length of the ports can be easily controlled during the design process to satisfy the above-mentioned condition. The MMI section width was set to 8 µm and both edges were connected to a 2-µm-thick oppositely off-centered singlemode waveguide of 3 µm width.…”

The recent rapid growth of data traffic is leading to high-speed communication for local areas, such as the fiber-to-the-home service. A semiconductor laser is used for such a purpose; however, there is the difficulty that an even higher frequency response occurs in only carrier-photon resonance. For this reason, it is effective to use a second resonance, such as a photon–photon resonance (PPR), for enhancing the frequency response, and the active multimode interferometer laser diode (active-MMI LD) is one of the candidates for achieving a high PPR frequency. In order to obtain an even higher PPR frequency, we have investigated the control scheme of enhancing PPR. In this work, we compared two types of active-MMI waveguide structures to confirm the scheme. As a result, a 3.8 GHz enhancement of the PPR peak, resulting in a 3 dB lower frequency response of 17 GHz, has been successfully achieved by waveguide geometry modification.

We report on linewidth narrowing and stabilization of semiconductor DFB laser implemented through its self-injection locking to an external fiber ring cavity in conjunction with an active optoelectronic feedback circuit controlled by a simple low-cost USB-DAQ card. The system enables narrowing of the DFB laser linewidth below ~0.5 kHz and drastically reduced the laser phase noise. Specifically, the laser configuration is fully spliced from the polarization maintaining (PM) single-mode optical fiber that exhibits significantly improved stability against the environment noise. Drastic narrowing of the DFB laser linewidth down to ~310 Hz and a phase noise less than -100 dBc/Hz (>30 kHz) are achieved with the PM fiber ring cavity built from a single fiber coupler. The reported PM laser configuration is of great interest for many laser applications where a narrow sub-kHz linewidth, simple design and low cost are important.
