Abstract

Short pulse generation by adiabatic tuning of light was reported. The photonic crystal nanocavity was used in the experiment as a width-modulated line defect cavity that is inline connected to input/output waveguides. a modulated output spectrogram, where a short wavelength component appears immediately after the modulation, even though we have not entered light at this wavelength. Another aspect of AWS is that it allows us to achieve dynamic control of the Q of the cavity, which is required to demonstrate photonic memory. AWS shifts the wavelength of the trapped light toward a shorter wavelength, and the light is immediately output into the waveguides and generates a short pulse. This is strengthens the coupling between the cavity and I/O waveguides, resulting in a low-Q mode.
