DESCRIPTION:Photons underpin our lives\, from our ability to see through t
 o our communication systems. While computers are built around electronics\
 , long-haul communications are built around light. Photonic integrated cir
 cuits (PICs) are the optoelectronic equivalent of the silicon chips that h
 ave revolutionised society over the last 70 years. PIC devices such as las
 ers\, modulators\, waveguides and detectors are widely used in communicati
 ons\, sensing\, healthcare and quantum technology. Optical communications 
 represents almost 60% of this market\, with PICs currently deployed mainly
  in the long-haul network. However\, because of society’s ever-increasin
 g demands for data\, they are migrating rapidly into the office and home. 
 \n\nPICs are also key to the next generation of magnetic disk drive techno
 logy for the cloud. Currently\, no other storage technology can meet the c
 ost/performance criteria\, but new approaches are needed to increase the s
 torage density. Heat-assisted magnetic recording (HAMR) involves local hea
 ting of magnetic media\, so data can be written at densities above 1 Tbit/
 in2. By integrating lasers\, waveguides and plasmonic antennas\, PICs focu
 s enough energy on the disk to raise the local temperature to up to 500 °
 C within 1 ns. The market for HAMR is expected to be billions of units per
  annum\, a truly exciting volume application for PIC technology.\n\nPlease
