“…The minimum force sensitivity of our AFM system, limited by thermal fluctuations, , can be calculated from F min = [(4 k B TkB )/(ω 0 Q )] 1/2 , where k B is the Boltzmann constant, T is room temperature, k is the spring constant of the cantilever (3 N/m), B is the bandwidth of measurement (set by lock-in amplifier) used in the force measurement (7.8 Hz), ω 0 is the resonant frequency of the AFM tip (∼101 kHz), and Q is the quality factor of the cantilever (∼160). This leads to a force sensitivity on the order of ∼40 fN in our setup.…”

We present spatial mapping of optical force generated near the hot spot of a metal-dielectric-metal bowtie nanoantenna at a wavelength of 1550 nm. Maxwell's stress tensor method has been used to simulate the optical force and it agrees well with the experimental data. This method could potentially produce field intensity and optical force mapping simultaneously with a high spatial resolution. Detailed mapping of the optical force is crucial for understanding and designing plasmonic-based optical trapping for emerging applications such as chip-scale biosensing and optomechanical switching.

“…Recently, SP based devices have been used for all-optical modulation [7][8][9][10][11]. More significantly, opto-mechanical coupling has been used for optical modulation and tuning [12][13][14], optical switching [11], photodetection [15,16], and optical gradient force sensing and manipulation [17][18][19]. Here, we present a method for controlling the shape and direction of an electromagnetic (EM) wave in the far field using SP based optical force method.…”

Controlling the far field pattern of the electromagnetic (EM) waves has many applications including wireless communications, radar detection, and industrial applications. The dynamic control of EM patterns is called beam steering. Despite advantages in each technique, the speed, angular range, and spectral range of beam steering is limited due to mechanical and optical properties of such systems. Here we present a beam steering method by means of an array of optomechanical nanoantennas in which the generated optical force of each antenna results in changes to the antenna response due to mechanical reconfiguration. As a result, the antenna far field phase is changed due to the mechanical movement generated by the optical force. Depending on the mechanical properties of the movable component of the antenna, the phase of the antenna can be tailored for a given optical source power. FDTD simulations are used to calculate the optical response of antenna. A phase array of optomechanical nanoantennas is used to do beam steering. The main far field lobe is steered by 0.5 degrees as a result of the mechanical reconfiguration of the phased array.

“…Highly sensitive light detection at short-wave infrared (SWIR) wavelengths is important for telecommunication applications, such as quantum key distribution and quantum computing [1][2][3][4][5] . Except for individual SWIR detectors, SWIR detector arrays are also crucial for telecommunication applications, as arrays can speed up applications like parallel quantum computing tremendously [6] .…”

Shortwave infrared (SWIR) detectors combining AlAs∕In 0.53 Ga 0.47 As∕AlAs double barrier structure (DBS) with In 0.53 Ga 0.47 As absorption layer are fabricated by molecular beam epitaxy. By adding a p-charge layer, the dark current density of the detector is lowered by 3 orders of magnitude. The responsivity of the detector is tested at room temperature, which reaches 6000 A/W when the power of the incident light is 0.7 nW. The noise equivalent power (NEP) of the detector at 5 kHz is measured to be 3.77 × 10 −14 W∕Hz 1∕2 at room temperature.
