Linear and Nonlinear Optical Properties of a Doubly Clamped Suspended Monolayer Graphene Nanoribbon Nanoresonator

“…The optical response of hybrid systems that make use of the interaction between different excitations, such as, for example, excitons from semiconductor quantum dots or molecules and plasmons from metallic nanoparticles, have attracted the interest of recent studies due to the enhanced nonlinear and quantum optical effects that the hybrid systems may offer, as compared to their uncoupled constituents [ 1 , 2 , 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 ]. Another important category of hybrid systems investigated for their enhanced nonlinear optical response are those emerging due to the coupling between excitons in quantum dots and phonons in nanoresonators [ 20 , 21 , 22 , 23 , 24 , 25 , 26 , 27 , 28 , 29 ]. In these latter studies, the quantum system was described as a two-level system interacting with a weak probe field that was also strongly pumped by a coherent coupling field.…”

“…The type of the nanoresonator that was used differed in the various studies; the quantum system was coupled to a suspended Z-shaped graphene nanoribbon [ 20 , 21 , 22 ], a carbon nanotube [ 23 , 24 , 25 ], a monolayer MoS2 suspended on a Si/SiO 2 substrate [ 26 ], or DNA molecules [ 27 , 28 , 29 ]. In these hybrid systems, the main nonlinear optical effects that have already been studied are the linear dispersion/absorption under coherent pump–probe excitation and the cross-Kerr nonlinearity under the action of a strong pump field.…”

“…Specifically, we analyzed the optical properties of a hybrid structure that was composed of a quantum dot and a doubly clamped suspended graphene nanoribbon nanoresonator, similar to that studied in [ 20 , 21 , 22 ]. Graphene-based nanomechanical resonators have been studied for over 15 years and have very interesting properties [ 30 , 31 , 32 ].…”

Pseudo-atomic orbital behavior in graphene nanoribbons with four-membered rings

“…Early research largely focused on the potential role of GNRs in field-effect transistors (3,4), revolving around tailoring the size of their bandgap through width, edge, and heteroatom engineering (2,(5)(6)(7), as well as the formation of heterojunctions through copolymerization (5,8). Recently, the design of ever more intricate GNR structures has opened new avenues of exploration, including topics such as negative differential resistance (9)(10)(11)(12), spintronics (13,14), magnetism (15)(16)(17)(18)(19)(20), and quantum information processing (21)(22)(23).…”

Effective Control of the Optical Bistability of a Three-Level Quantum Emitter near a Nanostructured Plasmonic Metasurface

“…Various phenomena have been studied in such media, including the manipulation of spontaneous emission [13][14][15][16], Fano effects in energy absorption [17][18][19][20], slow light and optical transparency [21][22][23], enhancement of the refractive index [24], modification and enhancement of the Kerr nonlinearity [25][26][27][28], four-wave-mixing [29,30], inversionless gain [31][32][33][34][35][36], OB or optical multistability (OM) [37][38][39][40][41][42][43][44][45][46][47][48][49], and many others [50][51][52]. The contemporary fabrication methods [53][54][55][56] for realizing plasmonic nanostructures incorporating quantum emitters [57] enable the experimental verification of the above phenomena.…”
