Abstract: A method of coding based on transition of lasing and non-lasing states of an optical structure. The power of a single pulse within picosecond-scale time is regulated to achieve transition of lasing and non-lasing states of an optical structure capable of emitting light and having the characteristic of resonant cavity and high Q value along a light path created by a combination of optical elements such as beam splitters, adjustable reflectors and continuously adjustable attenuators. Due to different parameters carried by light radiation in the two states, the parameters correspond to “1” and “0”, respectively. Therefore, binary high-bandwidth coding is realized, and even ternary coding can be realized with a slight improvement on the basis of the light path of binary coding. The tunable bandwidth of coding may reach up to 0.1 THz, which is conducive to promoting the development of high-bandwidth information processing optical microchips.
