Embodiment Construction

[0034] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] An embodiment of the present invention provides an etalon packaging structure. figure 1 It is a structural schematic diagram of an etalon packaging structure according to an embodiment of the present invention; as figure 1 As shown, the encapsulation structure of the etalon includes: an etalon 11 and a temperature-sensing structure 12, and the temperature-sensing structure 12 is connected to the etalon 11 through a connecting piece 13;

[0036] The size of the temperature-sensitive structural member 12 changes as the ambient temperature changes;

[0037] When the size of the temperature-sensitive structural member 12 changes, the connecting piece 13 drives the etalon 11 to rotate, and the rotation of the etalon 11 is used to change the reflection of the beam in the etalon 11 angle;

[0038] Wherein, the change of the tempera...

Abstract

The embodiment of the invention discloses an etalon packaging structure and a wavelength locking device. The package structure of the etalon includes: an etalon and a temperature-sensing structure, the temperature-sensing structure is connected to the etalon through a connecting piece; the size of the temperature-sensing structure changes with the change of the ambient temperature; When the size of the temperature-sensitive structural member changes, the connecting piece drives the etalon to rotate, and the rotation of the etalon is used to change the reflection angle of the beam in the etalon; wherein, the The change in temperature and the change in the angle of reflection of the beam within the etalon keeps the peak transmission wavelength of the beam at the etalon constant.

Description

technical field [0001] The invention relates to the technical field of optical fiber communication, in particular to an etalon packaging structure and a wavelength locking device. Background technique [0002] In an optical communication network, replacing multiple fixed-wavelength lasers with adjustable lasers can effectively reduce system complexity and simplify system modes. However, during the lifetime of the tunable laser, due to the aging of the laser, the wavelength may drift, and this wavelength drift will cause crosstalk between adjacent channels, resulting in bit errors in the system. [0003] At present, the wavelength drift can be eliminated by re-calibrating the wavelength of the laser with the wavelength locking device, and the laser wavelength can be tuned to the specified wavelength. The wavelength locking device generally uses an etalon or a thin film filter to calibrate the wavelength, and the wavelength of the etalon or thin film filter is more sensitive ...
