A method of altering a refractive property of a crosslinked acrylic polymer material by irradiating the material with a high energy pulsed laser beam to change its refractive index. The method is used to alter the refractive property, and hence the optical power, of an implantable intraocular lens after implantation in the patient's eye. In some examples, the wavelength of the laser beam is in the far red and near IR range and the light is absorbed by the crosslinked acrylic polymer via two-photon absorption at high laser pulse energy. The method also includes designing laser beam scan patterns that compensate for effects of multiphone absorption such as a shift in the depth of the laser pulse absorption location, and compensate for effects caused by high laser pulse energy such as thermal lensing. The method can be used to form a Fresnel lens in the optical zone.

This invention discloses a mid-to-far-infrared narrowband light source for MEMS, comprising a substrate, a suspension support layer, a heating resistor layer, and a radiation functional layer. The substrate is a silicon substrate. The suspension support layer is fixed to the substrate by anchor points. The heating resistor layer is disposed on the suspension support layer, and the radiation functional layer is disposed above the heating resistor layer. The suspension support layer and the heating resistor layer have Y-shaped grooves forming a Y-beam suspension structure. The Y-beam suspension structure is connected to the substrate by anchor points to form thermal isolation. The surface of the radiation functional layer has a periodically arranged array of micro / nano structures. The period and size of the micro / nano structure array are on the same order of magnitude as the target infrared wavelength, forming an artificial interface with specific equivalent refractive index and resonance characteristics to achieve narrowband spectral output. This invention can reduce heat conduction from the radiation region to the substrate, reduce heat conduction loss, reduce heat leakage, improve thermal isolation performance, and reduce heat capacity, thereby enabling the beam to heat up and cool down rapidly.
