| 英文摘要 | In some applications of distributed feedback (DFB) lasers, it is important that the coupling constant κ be closely controlled. This is not easily achieved, frequently resulting in low yield of acceptable devices. I have discovered that variations in κ can be reduced if the DFB laser is designed such that the thickness ts of a spacer layer (between the active layer and the Bragg grating) is within about ± 10% of the value to/(1 - α), where to is the modal decay length, and α is a parameter which characterizes the fractional variation of to with fractional changes in layer thickness. |
