We describe the main recent technological approaches that associate micro‐optical
elements to VCSELs in order to control their output beam and to improve their photonic …

This paper presents a micro XY stage that employs electrostatic comb-drive actuators and
achieves a bi-directional displacement range greater than 225 µm per motion axis. The …

The light-emitting diode (LED) has been the subject of much interest in the role of a backlight
module for liquid crystal displays (LCDs). However, a traditional LED lamp is a point-light …

We present a free-space optical interconnect system capable of dynamic closed-loop optical
alignment using a microlens scanner with a proportional integral and derivative controller …

We report on the design and fabrication of polymer microlenses fabricated on patterned SU-
8 layers in view of integrating microlenses on VCSEL arrays for laser beam shaping. For a …

We present an integrated beam steering system with a microlens scanner and a vertical
cavity surface-emitting laser (VCSEL) source. The scanner and the VCSEL are assembled …

The design, fabrication, and characterization of an electrothermally actuated lens scanner
with bistable mechanical brakes, for the application of free-space board-to-board optical …

Femtosecond laser direct writing (FLDW) has been widely employed to create volumetric
structures in transparent materials that are applicable as various photonic devices such as …

In this paper, we discuss the design, fabrication, and characterization of electrothermally
