Embodiment 1
[0050]The embodiment of the present invention provides an emission optical power stabilization component based on optical path displacement compensation (several typical structures are shown in the following embodiments of the present invention, for example figure 2 , Figure 5 , Figure 9 , Figure 11 and Figure 14 shown), including lasers, lenses and fiber coupling ports, specifically:
[0051] The laser, the lens, and the fiber coupling port are arranged on the first substrate and the second substrate according to a preset arrangement strategy; wherein, the expansion coefficient of the second substrate is greater than that of the first substrate.
[0052] The arrangement strategy makes the initial distance between the laser and the lens, the lens and the fiber coupling port, and / or the laser and the fiber coupling port compare with the optimal coupling distance deviation preset value of the optimal coupling point;
[0053] Theoretically, there can be multiple groups o...
Embodiment 2
[0078] The embodiment of the present invention provides the specific implementation content when the object used to generate the default value deviation is a lens in the method one proposed in the first embodiment during the initial setting process. It should be pointed out that in the first embodiment The specified value described is specifically expressed as the first specified distance Δl in the embodiment of the present invention 1 . The embodiment of the present invention proposes a component for stabilizing the transmitted optical power based on optical path displacement compensation, such as Figure 2-Figure 6 As shown, it includes a laser 1, a lens 2 and a fiber coupling port 4 (because the optical isolator 3 is a non-critical feature in each embodiment of the present invention—that is, it does not affect the position of the best coupling point, so it is not included in each embodiment presented in a formal content form, but only shows its existence in some drawings),...
Embodiment 3
[0101]In Embodiment 2, the first method introduced in Embodiment 1 is provided, specifically by setting the position of the lens 2 to form the structural relationship of the initial state (compared with the optimal coupling distance deviation preset value of the optimal coupling point). In the specific implementation process, since the fixed objects in the processing include lasers and fiber coupling ports, in addition to the method 1 proposed in embodiment 2 to realize embodiment 1 by setting the position of lens 2 , Embodiment 3 of the present invention will further explain how to realize the initial state in the first way by adjusting the laser 1 . Among them, the basic structure can refer to image 3 and Figure 5 To achieve, the next content, will pass Figure 7 Specifically, how to arrange the initial distance between the laser and the lens, so as to form the optimal coupling distance deviation preset value from the optimal coupling point (in the embodiment of the pres...
