Introduction

As a result of the increasing demand for smaller, more advanced optical devices, a field called nano-optics is quickly emerging,focusing on the research and design of next generation optical devices. Incorporation of nanoengineering within optical design is a decidedly promising venture, and is sure to yield tremendous advancements to benefit all walks of life. However, in tandem with the rise of the relevancy of nanotechnological engineering comes the need for more advanced adhesive systems capable of high quality performance with no margin of error. It is for this market that Master Bond has developed a leading product line of adhesive formulations specially designed for performance in the nano-optical industry.

Anticipated Applications

Following are some of the many expected Nano-Optical developments:

Nano size electro-optic modulators

• Nano size electro-optic modulators will offer increased speed and efficiency for nano scale communication networks.

Electro-optic switches

• To be employed in semiconductors for high speed devices with low power consumption.

Photonic crystals

• To be used in fiber optic cables for increased transmission quality as well as wavelength division

Sensors

• Nano engineered photonic sensors will serve as a highly efficient method of data conversion

Multiplexers

• A nanotechnological device for combining numerous data streams holds much promise for use in communication networks.

Nanowires for Optical Applications

Nanowire engineering is a tremendous focus for design and implementation of novel nanotechnological designs. Their unique optical properties make them especially suitable for employment in next generation photonic devices. Nanowires utilize a revolutionary ‘bottom up’ process, a form of engineering which represents a positive departure from the conventional ‘top bottom’ approach. The ‘bottom up’ approach allows for the controlled assembly of nanoscale components into functional systems, a process which through complex molecular manipulations has allowed for the extensive integration of nanowires in photonic devices including diodes, lasers, detectors, and waveguides. A unique aspect of nanowire design, essentially the ability to control nanowire composition and in consequence the resulting bandgap, has shown tremendous potential for use in nanophotonic devices meant for the generation, waveguiding, and detection of light at the nanoscale. With all the emphasis engineers have been placing on nanowire optics, time is the only factor in the way of the implementation of highly advanced next generation photonic devices.

Looking to the Future

The unique flexibility and transparency of nanowires makes them suitable for employment in quite a number of futuristic applications. Among some of the most interesting would be navigational devices applied directly on a driver’s windshield. Engineers are currently involved in the development of such a design, and are hopeful that product commercialization is just around the corner.
