Description
Technical field
The utility model relates to the organic 2 D photon crystal defective of a kind of tunable wavelength mode laser device, particularly relates to a kind of organic 2 D photon crystal defective of tunable wavelength mode laser that is used in photon integrated chip.
Background technology
Conventional laser in the past is by resonance and diffraction and the light amplification of provision wavelengths is made laser generation, just needs complicated technology like this for chip is integrated.The mechanism that the proposition of photonic crystal has been showed a kind of new control photon to people is for the development in fields such as mechanics of communication, photoelectron technology has brought new vigor and vitality.In recent years, people have developed the new pattern laser light source that uses photon crystal device.For traditional semiconductor laser, revising the light beam field pattern far-field distribution of output plane (promptly), that optics mode is become is unsettled multi-modal, therefore find one can control optical field distribution to keep the mechanism of single-mode oscillation again under large tracts of land be very important, and refraction coefficient to be the 2 D photon crystal of periodic distribution be the selection that has potentiality.Utilize high-performance photon crystal micro-resonant cavity can produce low critical power, high frequency range and high efficiency organic 2 D photon crystal defective mould laser.The organic 2 D photon crystal defective of tunable wavelength mode laser can be integrated in various photon crystal optics elements on the chip, realizes that photon is integrated, and has volume advantage little, low in energy consumption.
Summary of the invention
For traditional semiconductor laser, revise the light beam field pattern far-field distribution of output plane (promptly), it is unsettled multi-modal to cause optics mode to become, and this is the deficiency of conventional laser.The utility model provides a kind of can control optical field distribution can be kept the machine-processed 2 D photon crystal tunable wavelength of single-mode oscillation simultaneously again under large tracts of land laser.
The technical scheme that its technical problem that solves the utility model adopts is: what this device adopted is layered structure, and from bottom to top stack is respectively substrate, covering thin layer, 2 D photon crystal, organic gain material.Its outside is a containment vessel; laser beam expander is fixed on the containment vessel; the optical pumping excitation is over against 2 D photon crystal one end; 2 D photon crystal is to constitute by covering the air column subarray that two-dimensional and periodic is arranged in the thin-layered medium material; defective is introduced in the position therebetween, places two liquid crystal posts in position, defective both sides of the edge.
The beneficial effects of the utility model are: in photon crystal structure, introduce defective, light by local in defective.Utilize two liquid crystal posts to regulate defect cavity control spontaneous radiation, thereby show strong quantrm electrodynamics effect.This defect cavity can be taken into account the chamber quality factor of superelevation and extra small chamber mode volume simultaneously, is the laser of ultralow threshold value.This laser is integrated at photon as light source, extremely important to the control of single photon in quantum information and the counting system, have a wide range of applications.
