“…Obviously, S-QP switching is the transition from steady state to complete QP state. It is worth noting that a similar S-QP switching was recently also found in a distributedfeedback (DFB) semiconductor laser with optical feedback [25], but its evolution is different from that in the VCSEL reported in this work. For the DFB laser, the duty cycle of QP oscillation first increases and then decreases to zero as feedback strength increases, and therefore the S-QP switching will finally evolve into a steady state.…”

Two new dynamic-state switching phenomena are experimentally observed in a vertical-cavity surface-emitting laser with polarization-preserved external-cavity optical feedback. One is switching between a steady state and a quasi-periodic state, and the other is switching between two different steady states. Both switching phenomena occur in the same polarization and the switching period is equal to the round-trip time in the external feedback cavity. The evolution of the two switching phenomena is experimentally investigated in detail. This work not only enriches the understanding of laser nonlinear dynamics but also provides an all-optical alternative for generation of special signals for possible applications.

“…In steady state, an LD with EOF can be utilized to detect the Doppler shift, vibration, velocity measurement, and displacement [5][6][7][8]. In P1 state, the optical injection and optical feedback schemes were used to generate microwave [9][10][11]. In work [9], a periodic switching between two nonlinear dynamic states caused by optical feedback is demonstrated.…”

With external optical feedback (EOF), a laser diode (LD) can operate at different dynamic states. In this work, an LD with EOF is set at period-one (P1) oscillation state to generate microwave photonic (MWP) signal for sensing. Firstly, the P1 state boundary of the LD is determined and then the influence of the LD controllable parameters on the boundary is studied by solving the well-known Lang-Kobayashi equations. A set of parameters selection rule for designing an LD based MWP sensing system is obtained. In addition, a measurement algorithm for recovering the displacement from an MWP sensing signal is developed. By making full use of the sensing information carried in both amplitude and frequency of the MWP signal, displacement sensing with high resolution and large range can be achieved. Both simulations and experiments are conducted to verify the proposed method and show it is capable of realizing wide measurable range, high measurement sensitivity, and high resolution sensing.

“…Here we use a well-known laser system that displays a rich variety of dynamical behaviors (a semiconductor laser with optical feedback [7][8][9][10][11]) as a testbed to study entrainment experimentally. The laser operates in the so-called low frequency fluctuations (LFFs) regime, in which the output intensity displays abrupt dropouts.…”

The entrainment phenomenon, by which an oscillator adjusts its natural rhythm to an external periodic signal, has been observed in many natural systems. Recently, attention has focused on which are the optimal conditions for achieving entrainment. Here we use a semiconductor laser with optical feedback, operating in the low-frequency fluctuations (LFFs) regime, as a testbed for a controlled entrainment experiment. In the LFF regime the laser intensity displays abrupt spikes, which can be entrained to a weak periodic signal that directly modulates the laser pump current. We compare the performance of three modulation waveforms for producing 1:1 locking (one spike is emitted in each modulation cycle), as well as higher order locking regimes. We characterize the parameter regions where high-quality locking occurs, and those where the laser emits spikes which are not entrained to the external signal. The role of the modulation amplitude and frequency, and the role of the dc value of the laser pump current (that controls the natural spike frequency) in the entrainment quality are discussed.
