15 Integrated ring resonators and narrowing of the laser bandwidth terms
Apodization
Noun
Apodization is used to purposely change the input intensity profile of an optical system, and may be a complicated function to tailor the system to certain properties.
Example: Future work includes grating APODIZATION to increase SMSR and reduce multimode effects, as well as improved design of the ring in the RAE-DBR to minimize losses.

Appealing
Adjective
attractive or interesting.
Example: An APPEALING approach is to stabilize a diode laser via self-injection locking (SIL) to an eigenfrequency of a high-Q whispering gallery mode (WGM) crystalline or integrated microring resonator.

Attainability
Noun
The state of being achievable.
Example: This confirms the assumption of ATTAINABILITY of ultra-high Q factors in silicon WGM microresonators in the mid-IR.

Fidelity
Noun
The degree of exactness with which something is copied or reproduced
Example: ULN is a key requirement to any system involving op- tical mixing, because the noise of the laser will directly affect the FIDELITY of the generated RF signals.

Foundry-compatible
Adjective
Foundry-compatible means that smth ready for implementation in industry.
Example: We compare several low-loss wave- guide platforms based on FOUNDRY-COMPATIBLE materials such as silicon, silicon nitride, and indium phosphide in Table 1.

Full-width half maximum (FWHM)
Noun
An expression of the extent of a function, given by the difference between the two extreme values of the independent variable at which the dependent variable is equal to half of its maximum value
Example: Weakening the grating decreases the FULL-WIDTH HALF MAXIMUM (FWHM) of the grating and lowers the reflectivity.

Proximity
Noun
Nearness in space, time.
Example: The second term in Eq. (1) becomes a significant part of the locking range only in close PROXIMITY of the coupler, where κmc is large.

Rib waveguide
Noun
A waveguide in which the guiding layer basically consists of the slab with a strip (or several strips) superimposed onto it.
Example: The geometry of the waveguide consists of a very shallow RIB WAVEGUIDE that is etched only 56 nm out of 500 nm.

To permit
Verb
Allow (someone) to do something.
Example: Moreover, Si3N4 PERMITS hybrid integration with InP, offering fully on-chip narrow-linewidth lasers.

To preclude
Verb
Prevent from happening; make impossible.
Example: However, as discussed previously, this absence of interaction PRECLUDES many important applications of dual-SIL.

To recede
Verb
Move back or further away from a previous position.
Example: One may see that FLR + BLR is a bit wider when the microresonator RECEDES from the coupler, which is caused by the hysteresis of the piezo element.

ru: Удаляться, отдаляться
To suffer
Verb
To sustain loss or damage.
Example: It is also promising for free-space optical communication due to better performance than the near-IR light in fog conditions because it SUFFERS less from atmospheric turbulence.

To sweep
Verb
To move swiftly and smoothly.
Example: Then, turn on both lasers simultaneously and SWEEP their frequencies through the SIL regions to make a fine adjustment of the optical scheme to maximize the SIL range for both lasers simultaneously.

To sweep through
Verb
Succeed at easily.
Example: When one of the laser lines IS SWEPT THROUGH a microresonator resonance, we observe collapse of the emission spectra into a single line accompanied by a dip in transmission due to the coupling to the microresonator.

Adjective
