零间隙 meaning in English
zero clearance
zero stand-off
Examples
- The optical switch with double - heterostructure gaas / gaalas has low switching - voltage and light loss . and the boa - type optical switch utilizes maximum modal dispersion ( a p ) , does not require a specific fabrication length or length range to operate , has simple structure , and can exhibit very high extinction - ration from its two output ports ; so it is suitable for a 2 x 2 unit of optical switch array
而boa型结构(或称为零间隙定向耦合型)光开关利用了最大的模色散( ) ，不需要严格控制特殊的制造长度或制造范围，结构简单，从其两个输出端可以得到很高的消光比，是一种很好的2 2波导型光开关单元，同时也是光开关阵列的一种较好的选择。
