A method of fabricating a compound light-guide optical element (LOE) is provided. A bonded stack of a plurality of LOE precursors and a plurality of transparent spacer plates alternating therebetween is bonded to a first optical block having a plurality of mutually parallel obliquely angled internal surfaces. The block is joined to the stack such that first plurality of partially reflective internal surfaces of the block is non-parallel to the internal surfaces of the LOE precursor.

At least one compound LOE is sliced-out of the second optical block by cutting the second block through at least two consecutive spacer plates having a LOE precursor sandwiched therebetween.

A method for producing a plastic optical fiber including a step of dispersing a pigment in a curable composition containing an active-energy-ray-curable resin and the pigment, and a step of forming a coloring member made from a cured product of the curable composition by applying the curable composition on a peripheral surface of a plastic optical fiber body. The curable composition has a viscosity of 2,000 mPa or more and 3,000 mPa or less at 25° C. In the step of dispersing the pigment, the curable composition is charged into an airtight container having a circular tubular shape with an axis A1 and the airtight container is rotated around the axis A1 intersecting with a vertical line at a circumferential velocity of 0.02 m/sec or more and 0.2 m/sec or less.

The present disclosure relates to methods of forming a fiber optic core, and a fiber optic component with a highly uniform cladding covering the fiber optic core. In one microfabrication process a first sacrificial tubing is provided which has a predetermined inner diameter. A quantity of a curable polymer is also provided. The first sacrificial tubing is at least partially filled with the curable polymer. The curable polymer is then cured. The first sacrificial tubing is then removed to produce a finished fiber optic core. Additional operations may be performed by which the fiber optic core is placed inside a thermoplastic tubing, which is itself placed inside a sacrificial heat shrink. Heat is applied to reflow the thermoplastic tubing around the fiber optic core, thus forming a highly uniform thickness cladding. When the sacrificial heat shrink tubing is removed a finished fiber optic component is present. Additional microfabrication methods are disclosed which involve dip coating a pre-formed fiber optic core in a polymer, and then curing the polymer to form a finished fiber optic component with a uniform thickness cladding.
