Microphotonics is a branch of technology that deals with directing light on a microscopic scale. It is used in optical networking.\n\nSee link below

A laser is composed of an active laser medium (gain medium) and a resonant optical cavity.\n\nThe gain medium transfers external energy into the laser beam. It is a material of controlled purity, size and shape, which uses a quantum mechanical effect called stimulated emission to amplify the beam. The gain medium is pumped by an external energy source, such as electricity or light (a flash lamp or another laser). The pump energy is absorbed by the medium, producing excited states. When the number of particles in one excited state exceeds the number of particles in some lower state, population inversion is achieved. In this condition, an optical beam passing through the medium produces more stimulated emission than the stimulated absorption so the beam is amplified. An excited laser medium can also function as an optical amplifier. \nThe light generated by stimulated emission is very similar to the input signal in terms of wavelength, phase, and polarization. This gives laser light its characteristic coherence, and allows it to maintain the uniform polarization and monochromaticity established by the optical cavity design.\nThe resonant cavity contains a coherent beam of light between reflective surfaces so that each photon passes through the gain medium multiple times before being emitted from the output aperture or lost to diffraction or absorption. As light circulates through the cavity, passing through the gain medium, if the amplification in the medium is stronger than the resonator losses, the power of the circulating light can rise exponentially.

Possibly.\n\nEven probably one day.\n\nProfessor John Pendry has done the math to show that theoretically metamaterials can be used to make light flow around objects in a similar way to water waves flowing round obstacles. Far enough away from the object, the wave flow is barely disrupted, so it cannot be seen.\n\nNow it just needs to be turned into practice.

A laser (from the acronym Light Amplification by Stimulated Emission of Radiation) is an optical source that emits photons in a coherent beam. The verb to lase means "to produce coherent light" or possibly "to apply laser light to", and is a back-formation of the term laser.\n\nLaser light is typically near-monochromatic, i.e. consisting of a single wavelength or color, and emitted in a narrow beam. This is in contrast to common light sources, such as the incandescent light bulb, which emit incoherent photons in almost all directions, usually over a wide spectrum of wavelengths.\n\nLaser action is explained by the theories of quantum mechanics and thermodynamics. Many materials have been found to have the required characteristics to form the laser gain medium needed to power a laser, and these have led to the invention of many types of lasers with different characteristics suitable for different applications.\n\nThe laser was proposed as a variation of the maser principle in the late 1950s, and the first laser was demonstrated in 1960. Since that time, laser manufacturing has become a multi-billion dollar industry, and the laser has found applications in fields including science, industry, medicine, and consumer electronics.

Micro electronics that you could see through. Nanobot technology. Using the contact lens as a focus lens. Tapping into the human body's natural electricity as a power source. Possible in a few years. \n\nIf the contact was a colored contact you couldn't see through, highly possible now.

2) Use stop wave:\nPlace a speaker of known, variable frequency close to a micro, the micro is connected to a microamperemeter.\nPlace that in the top of a long glass tube, slowly fill the tube with water until the the microamperemeter show a maximum. Continue filling the tube with water to get the next maximum. The distance between the two consecutive maximums is half the wavelength.\nSpeed = wavelength x frequency.\nRepeat the experiment several times and get the averange. That should be close to actual value.

I am in a Microbiology college course. The closest I can come to your question from my text is about 50 NM (nanometer).
