Is it advisable to have on-chip optical termination that blocks light to propagate for short period of time. What will be impacts, field experts can share your views here...
Greetings.
1. Specify what functionality (function) is performed by this node and for what: "... an optical terminal device that blocks the propagation of light for a short period of time ..." - what is meant?
2. As is known, the functionality of a node determines its design.
The function you specify may (alternatively) be present, but not be involved in some modes - see below:
a. If it is an optical modulator and / or switch and / or logic element (for example, on LiNbO3, etc.), then, apparently, YES;
b. If this is a simple Y-like splitter (see your and colleagues' article: ... Configurable Photonic Element: Analysis and Design towards Reconfigurable Photonic ICs ...) - then, apparently, NO;
c. If it is a combined node: cases a and b; a or c; their combinations -YES.
P.S. A Y-like splitter for photon (optoelectronic) ICs can play the role of a part of the logic circuit n OR-NOT (Pierce basis) on the basis of which any digital device or automaton is built. See: nOR-NOT type SUPROSTD high-speed universal optoelectronic logic element. Inventor(s) N Proskurin & other, 2001/02/15; The patent №32921А (UA), application № 98073980, 1998/07/21.
Sincerely, Nick Proskurin, PhD.
Nick Proskurin your answer is great.. we are designing a 1x1 photonic switch based on directional coupler. The ON state is represented by light propagation in the bar waveguide and the OFF state is represented by cross waveguide. In the absence of voltage the light will be coupled to the cross waveguide, where the optical termination is required. How the optical termination is considered in BPM based design approach and also share the impact of coupled light such as scattering effect and heating effect.
Thanks in advance...

2. Effective absorber of incoherent radiation can be a photodiode (or their n layered structures according to the 1,2...n wavelengths of the spectrum) in the photovoltaic mode (up to 30 ... 44% can be converted into electrical energy, the rest into heat).
3. Their combination in different ratios.
Or your option. Nick proskurin
