“…1, the modular optical nanocircuits experimentally demonstrated here may indeed pave the way towards the realization of a wide range of filter responses based on lumped optical nanocircuit elements. We should emphasize that the nanocircuit paradigm unveiled by our experiments is significantly more powerful than equivalent circuit models for photonic structures previously developed [23][24][25] . Rather than modelling a distributed photonic system with an equivalent circuit, our work shows that it is actually possible to synthesize a photonic circuit functionality by assembling modular lumped nanoelements, providing a one-to-one correspondence between the desired circuit response and the topological design.…”

A key element enabling the microelectronic technology advances of the past decades has been the conceptualization of complex circuits with versatile functionalities as being composed of the proper combination of basic 'lumped' circuit elements (for example, inductors and capacitors). In contrast, modern nanophotonic systems are still far from a similar level of sophistication, partially because of the lack of modularization of their response in terms of basic building blocks. Here we demonstrate the design, assembly and characterization of relatively complex photonic nanocircuits by accurately positioning a number of metallic and dielectric nanoparticles acting as modular lumped elements. The nanoparticle clusters produce the desired spectral response described by simple circuit rules and are shown to be dynamically reconfigurable by modifying the direction or polarization of impinging signals. Our work represents an important step towards extending the powerful modular design tools of electronic circuits into nanophotonic systems.

“…If the resonators are small enough so that the spacing of the resonant frequencies accommodates the set of WDM channels within the communications window, the goal of dropping one channel by one filter without affecting the other channels is achieved. One proposed version uses distributed feedback (DFB) resonators side-coupled to the signal bus [2]. In order to remove all of the power in one channel, two such resonators are required.…”

Abstract-The operation principle of resonant channel add-drop filters based on degenerate symmetric and antisymmetric standing-wave modes has been described elsewhere using group theoretical arguments. In this paper, the analysis is carried out using coupling of modes in time. A possible implementation of such a filter is a four-port system utilizing a pair of identical single-mode standing wave resonators. The analysis allows a simple derivation of the constraints imposed on the design parameters in order to establish degeneracy. Numerical simulations of wave propagation through such a filter are also shown, as idealized by a two-dimensional geometry.

“…For instance, it allows an optical communication link to be partitioned into many channels where signals can be selectively transmitted and detected. Applications can be found in [17] and [16]. The parameters used in the design of the filter determine many of its relevant properties, and it is of interest to simulate the filter numerically to anticipate the influence of these parameters.…”
