Microlens Array Formation and Alignment

Microlens array formation and alignment to heterogeneously integrated optoelectronic devices. Optoelectronic devices are printed or transferred in a single process step while also creating inactive optoelectronic devices that are precisely shaped for alignment purposes rather than for optical or electrical performance. Microlenses are integrated monolithically. The microlenses are aligned directly to a fiducial generated by the device integration step, reducing overall misalignment. Additionally, we use specific optical designs for the lenses to add novel functionalities to the system. By designing the lenses with engineered offsets, distances and curvatures with respect to the arrays of optoelectronic devices, we control properties of light such as: angles, phase, beam widths, and wavelength dependence.
