| 1. | an inconvenience of prism couplers is that the prism material must have a high refractive index .
棱镜耦合器的一个不方便的地方是棱镜材料必须有较高的折射率。 |
| 2. | For many purposes, however, the above description is quite adequate in explaining the major features of the prism coupler .
然而，对许多用途而言，用上述的说明来解释棱镜耦合器的主要特点是完全足够的。 |
| 3. | This principle is the basis for the operation of directional couplers, the implementation of which usually takes the form shown in fig. 3. 23 .
这个原理就是走向耦合器工作的依据，其装置一般具有图323所示的形式。 |
| 4. | It is interesting to observe that the principle of operation for the "prism" coupler of fig. 3. 22b is being considered for extracting the output from lasers of the mesa type .
我们将看到图322b的“棱镜耦合器”工作原理正被考虑用来从台面激光器获得出，这是很有意义的。 |
| 5. | Because the beam formed by a tapered coupler is produced by many rays that emerge at slightly different angles, the outgoing beam is characterized by a relatively large divergence .
因为尖劈耦合器形成的光束是由许多出射角稍有不同的光线组成的，放出射光束的特点是具有较大的发散度。 |
