In order to create an optical device with a photonic band gap extending in two dimensions and with very uniform properties in any direction and for any polarisation state, to within 1%, air holes are etched within a substrate of low refractive index material such silicon oxynitride or silica glass. The ratio of air hole area to the remainder of the substrate is low, being less than 35%. The air holes define a quasicrystal structure, having twelve fold symmetry, being based on a square-triangle system. In another development, an etched substrate with a regular crystal structure or quasicrystal structure exhibits a non-linear refractive index. Two adjacent areas in such a substrate have different lattice properties, or have defects in the lattices, to create a unidirectional transmission path (diode action). A further beam of light may be used to modulate the transmission path by reason of the non-linear refractive index.

A method for forming a MgO barrier layer in a tunnel junction magnetoresistive sensor (TMR). The MgO barrier layer is deposited by an ion beam deposition process that results in a MgO barrier layer having exceptional, uniform properties and a well controlled oxygen content. The ion beam deposition of the barrier layer includes placing a wafer into an ion deposition chamber and placing Mg target into the chamber. An ion beam from an ion beam gun is directed at the target thereby dislodging Mg atoms from the target for deposition onto the wafer. Oxygen is introduced into the chamber by one or both of pumping molecular oxygen (O₂) into the chamber and/or introducing oxygen ions into the chamber from a second ion beam gun. The use of ion beam deposition avoids oxygen poisoning of the Mg target, such as would occur using a more conventional plasma vapor deposition technique.
