testing threshold
解釋
診斷閾值-
The principle advantages of vcsels over conventional edge - emitting lasers lie in ultralow threshold current, small far - field divergent angle, high modulation frequency, potential for wafer level testing and the ease for single longitudinal mode operation and two - dimension integration. as a result they show considerable promise for applications such as optical fiber communication, parallel optical interconnects, optical information processing and neural networks, etc. a direct coupling theoretical model in quasi - three - dimension for the gain - wave guide vertical - cavity surface - emitting lasers has been created in this paper
它與傳統的邊發射激光器相比具有更優越的特性，例如，具有極低的閾值、較小的遠場發散角、調制頻率高、易實現單縱模工作和二維集成，無須解理封裝即可進行在片測試等，所以，它被廣泛應用於光纖通訊、并行光互聯、光信息處理、光神經網路等領域。 -
