Apparatuses and methods directed to an integrated circuit package having an optical component are disclosed. The package may include an integrated circuit die having at least one light sensitive region disposed on a first surface thereof. By way of example, the die may be a laser diode that emits light through the light sensitive region, or a photodetector that receives and detects light through the light sensitive region. An optical concentrator may be positioned adjacent the first surface of the first die. The optical concentrator includes a lens portion positioned adjacent the light sensitive region and adapted to focus light.

The present invention provides a photonic multi-bandgap structure, herein also referred to as photonic bandgap quasi-crystal (“PBQC”), that can direct light, having wavelength components within a selected passband (), from an input port, to a predefined output port, while providing an integrating element for Planar Lightwave Circuts. A photonic bandgap quasi-crystal of the invention combines in a planar waveguide spectrally selective properties of gratings, focusing properties of elliptical mirrors, superposition properties of thick holograms, photonic bandgaps of periodic structures, and flexibility of binary lithography. A photonic structure of the invention can be utilized, for example, as an integrating spectrally sensitive element in a variety of optical devices that can include, but are not limited to, optical switches, optical multiplexer/demultiplexers, multi-wavelength lasers, and channel monitors in Wavelength Division Multiplexing (WDM) telecommunications system.

A calibration standard simulates predetermined flying characteristics of a magnetic head for calibrating flying height testers. The standard comprises a substrate having a reflective layer supported thereon. A transparent layer is disposed over the reflective layer so that the reflective layer is disposed at a predetermined angle to a surface of the transparent layer, the predetermined angle representative of a predetermined flying angle of a head over a disk, the transparent layer having a thickness representative of a predetermined flying height of a head over a disk. A process for manufacturing and calibrating the calibration standard is also described.
