Embodiment Construction

[0074] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0075] A disorder-based multi-channel independently tunable local filter based on the reflector-cavity structure, adjusting the disorder factor of the reflector-cavity structure to determine the reflection coefficient of the reflector and / or the optics of the cavity Thickness, obtain multi-channel independent adjustable local filter;

[0076] Once the disorder factor is determined, the reflection coefficient in the reflector-cavity structure and the optical thickness of the cavity are determined accordingly;

[0077] The reflector-cavity structure includes N+1 reflectors (R 1 , R 2 ,...,R N+1 ) and N cavities (C 1 ,C 2 ,...,C N ),Such as figure 1 shown;

[0078] Wherein, the disorder factor of the reflector-cavity structure includes the disorder factor of the reflector (α 1 ,α 2 ,…,α N+1 ) and the disorder factor of the cavity (β 1 ,β 2 ,.....

Abstract

The invention discloses a disorder-based multi-channel independently-adjustable local optical filter and a designing method thereof. In designing of the local optical filter, the disorder of a reflector-cavity structure is regulated, and the intensity isolation degree serves as a criterion for a disorder regulation effect; through repeated optimization on the disorder of the reflector-cavity structure, all channel wavelengths and channel outer wavelengths reach the preset intensity isolation degree finally, which is reflected as the transmittance, approximate to 1, at the channel wavelength part and the transmittance, approximate to 0, at the channel outer wavelength part in the aspect of transmission performance. The adopted reflector-cavity structure can correspond to various physical realizations and well meet requirements of different application scenarios.

Description

technical field [0001] The invention belongs to the field of optical filters, in particular to a disorder-based multi-channel independently adjustable local optical filter and a design method thereof. Background technique [0002] "Nature" magazine published a paper in 2004, proposing that "disorder is a new order" and "disordered devices may have better performance than traditional ordered devices", see reference [1]. In a disordered medium, waves are localized inside the medium—that is, the Anderson localization effect, see reference [2]. [0003] The localization of waves in a one-dimensional disordered medium is represented by a series of randomly distributed resonant transmission wavelengths with higher transmittance and higher intensity distribution, see reference [3]. These resonant transmission wavelengths can be used to control the laser output spectrum and reduce the laser working threshold. The one-dimensional disordered media reported in the literature include l...
