“…The three-pulse photon echo (3PE) is a well-known technique which is applied to arbitrary waveform generation (AWG) and stores intense light pulses by a rare-earth-iondoped crystal (REIC). [1][2][3][4] Compared to the traditional waveform generation methods, this AWG technology enjoys unrivaled capabilities in terms of processing bandwidth and timeto-bandwidth product (TBP). According to the 3PE mechanism, the compressed echo sequences are generated by REIC and can be controlled to change their shapes by adjusting the chirp lasers, thus forming AWG.…”

We investigate the intensity and efficiency of a compressed echo, which is important in arbitrary waveform generation (AWG). A new model of compressed echo is proposed based on the optical Bloch equations, which exposes much more detailed parameters than the conventional model, such as the time delay of the chirp lasers, the nature of the rare-earth-iondoped crystal, etc. According to the novel model of compressed echo, we find that reducing the time delay of the chirp lasers and scanning the lasers around the center frequency of the inhomogeneously broadened spectrum, while utilizing a crystal with larger coherence time and excitation lifetime can improve the compressed echo's intensity and efficiency. The theoretical analysis is validated by numerical simulations.

Based on the similarity of paraxial diffraction and dispersion mathematical descriptions, the temporal imaging of optical pulses combines linear dispersive filters and quadratic phase modulations operating as time lenses. We consider programming a dispersive filter near atomic resonance in rare earth ion-doped crystals, which leads to unprecedented high values of dispersive power. This filter is used in an approximate imaging scheme, combining a single time lens and a single dispersive section and operating as a time-reversing device, with potential applications in radio-frequency signal processing. This scheme is closely related to a three-pulse photon echo with chirped pulses, but the connection with temporal imaging and dispersive filtering emphasizes new features.

Microwave photonic pulse generation has intrinsic high speed and large bandwidth, and it can overcome the sampling-rate limitation in the electrical domain. Herein, we propose a partly temporallyoverlapped photon echo scheme to generate microwave pulses with a high data transfer rate and precision pulse width. The partly overlapped chirped control pulse has the same chirped rate segments but different time delays. The time delay between the segments and the number of segments can be adjusted to achieve a controllable multipulse photon echo train. We developed a theoretical model based on the photon echo process and performed simulations to obtain nonlinear chirped periodic spectral grating in a Tm 3+ :YAG crystal and gave the time delay provided by the spectral grating to the probe pulse at different instantaneous frequencies. We further generated pulse code modulation signals to verify the performance of the target signal. The proposed signal-generation scheme has potential applications in microwave photonics and modern radar systems.
