Start early

• Photons - a sequence, thought through
• A future...
• Seeing
• Engineered spaces around the source
• Guiding photons
• A model to predict where photons will turn up
• Summary so far.
• A general tool
• Reflection
• Refraction
• Propagation
• Restricted paths for propagation
• Just two slits
• Engineering a lens
• Engineering a mirror
• Why bother, and what about...
• Photons, power, compensation
• Photons, devices, power, fractional absorbtion
• Photons and selective absorption
• Threshold effects
• Gifts from photons
