Tailoring the properties of an optical beam incident on a one dimensional metallic grating can attain a substantial control
over the excited surface plasmon polariton wave. In this work we derive the complete analytical relations between the
optical angles of incidence and the resulting surface plasmon propagation angle. These relations are demonstrated both
numerically and experimentally. Following we show that there is an optimal grating that can excite any surface plasmon
propagation angle between ±82.46 degrees and efficient polarization schemes which lead to negligible losses. Finally we
introduce a formalism that relates general surface plasmon beams to corresponding incident optical beams and using it
we demonstrate numerically a varying position surface plasmon hotspot generation.
Surface-plasmon waves have been utilized in many applications such as biological and chemical sensing and trapping,
sub-wavelength optics, nonlinear optics, optical communication and more. Controlling the shape and trajectory of these
waves is a key feature in enabling all of the above applications, and a challenging task. The fundamental challenges
resides in the different wave properties of surface plasmon waves, with comparison to free-space waves: First, coupling
a surface plasmon wave from a free-space wave requires a compensation for the missing momentum between the two
wave-vectors. Second, owing to the limited propagation length of surface plasmons and the limited measurement range
of their characterization tools, the resulting beams should be formed directly in the near-field. Third, unlike planar phase
plates, surface plasmons are excited over a finite propagation distance and therefore their phase cannot be simply defined
at a specific one-dimensional plane. Fourth, dynamic tools for controlling the wavefront of free-space beams, like
spatial-light-modulators, do not exist for surface plasmons. Here we demonstrate, both numerically and experimentally, a
robust holographic scheme that provides complete control over the amplitude and phase of surface-plasmons, thereby
enabling the engineering of any desired plasmonic light beam. We show how all of the above challenges can be
overcome by introducing a new class of binary plasmonic holograms, which are designed specifically for the near -filed.
We demonstrate a large variety of plasmonic beams, such as ”self-similar”, “non-diffracting", "self-accelerating", “selfhealing”,
paraxial and non-paraxial plasmonic beams, and also the dynamic generation of plasmonic bottle-beams for
micromanipulation of particles.
A high bandwidth optical interconnect is designed based on parallel optical VCSEL links. Large matrices with 168 data channels are utilized exhibiting the highest reported full duplex aggregate bandwidth of 1.34Tb/s. Optical links of 300m are measured with BER < 10-12 while the power efficiency is 10.2 pJ/bit. The interconnect design is that of hybrid device with the III-V optoelectronics assembled directly onto the ASIC using Au/Sn eutectic bonding. Optical packaging is enabled using fiber bundle matrices whose dimensions are identical to those of the optoelectronic chips. The entire chip is assembled onto a system PCB in telecom and datacom applications. The backplane of the system becomes passive optical backplane and is entirely fiber based. The hybrid integration allows for a 3-fold increase in the number of SerDes available on a single package to about 500 lanes.
