Abstract

The invention relates to a micro-nano fiber laser based on a microfiber phase-shifted Bragg grating (MPSBG). Air holes are formed through etching by utilizing a focusing ion beam system and therefore an MPSBG is formed. An optical micro-cavity in the middle of the MPSBG is filled with a composite (organic-inorganic) semiconductor crystal material CH3NH3PbI3 based on perovskite type nano-crystals, pulse laser with the wavelength being 60nm, the pulse width being 150fs and the repetition rate being 1kHz is adopted to serve as a pump light source, and thus laser with the wavelength being 788nm can be output. The optical micro-cavity formed by the microfiber phase-shifted Bragg grating (MPSBG) plays strong constraint and reflection roles in light. The micro-nano fiber laser is small in size, low in cost, low in threshold and high in integration, is easy to operate, and is a novel micro-nano fiber laser based on the microfiber phase-shifted Bragg grating (MPSBG). The low-cost, small-size, low-threshold and high integration micro-nano fiber laser can meet demands of all fields, especially the photoelectric integration field, in the future.
