Sentence examples for back facets from inspiring English sources

Both the front and back facets of the WG QD-EAM are as-cleaved and reverse bias of 0 5 V is controlled by a DC voltage supply.

Since reflection loss accounts for ~3 dB of the insertion loss [34], introducing AR coatings on both the front and back facets of our device will reduce the insertion loss to ~5 dB and make our insertion loss comparable to theirs.

Effect of the front and back facet reflectivities on output power of the laser diodes has been studied.

The Spectrophotometer results of the front facet transmission and the back facet reflection are in good agreement with the simulation results.

The optical output power of a laser diode can be enhanced by anti-reflection (AR) and high-reflection (HR) facet coatings, respectively, at the front and back facet.

These data were measured at the heat sink temperature of 20 °C, from the devices with HR coating on the back facet and no coating on the front facet.

The nanostructured HR and AR mirrors were deposited on the front and back facet of the laser respectively, by IBAD system under optimum condition.

The maximum back facet displacement is also noticeably reduced by up to 30% due to the densification and plastic deformation of the auxetic cores.

The waveguide was then cleaved to 2-mm-long cavities, and the high reflectivity (HR) coating consisting of Al2O3/Ti/Au/Ti/Al2O3 (200/10/10/100 nm) was evaporated on the back facet.

For edge-emitting QCLs, HR coating is commonly deposited on the back facet and leaving the front facet uncoated or PHR coated to reduce mirror loss meanwhile maintaining the optical power emitted from the front facet.

The optical transmission measurement setup consists of a superluminescent diode (SLED) incident onto the front facet of the WG QD-EAM, with transmitted power at the back facet detected by an optical spectrum analyzer (OSA).
