銘普光磁(002902.SZ):近日取得1項發明專利證書
格隆匯11月29日丨銘普光磁(002902.SZ)公佈,公司於近日取得一項中華人民共和國國家知識產權局頒發的發明專利證書,發明名稱為光模塊波長控制方法及裝置。
本發明實施例提供的光模塊波長控制方法及裝置,涉及波長控制領域,該方法包括:週期性地採集表徵光器件的熱敏電阻實際温度的電壓參數;獲取本週期熱敏電阻的目標電壓參數及實際電壓參數;根據本週期的熱敏電阻的目標電壓參數及實際電壓參數,計算累積電壓參數偏差值和週期電壓參數偏差值;根據本週期的累積電壓參數偏差值、本週期的週期電壓參數偏差值及上一週期的電壓參數偏差值計算半導體制冷器TEC器件電壓調整量;根據TEC器件電壓調整量控制TEC器件對光器件進行温度調整以調整光模塊的發光波長。根據TEC器件電壓調整量控制TEC器件對光器件進行温度調整以達到調整光模塊的發光波長的目的,調試難度低,温度可控性較高,能快速穩定波長。
