A new, homemade sample holder enables precise two-dimensional nanopositioning for chip-scale near-field microscopy. This system integrates long-range stages and piezoelectric actuators for enhanced accuracy and repeatability.

Area of Science:

  • Instrumentation and Measurement
  • Microscopy
  • Nanotechnology

Background:

  • Accurate nanopositioning is crucial for advanced microscopy techniques.
  • Characterizing highly integrated optical structures requires high-resolution imaging capabilities.
  • Existing systems may lack the necessary range or precision for chip-scale analysis.

Purpose of the Study:

  • To develop a cost-effective, homemade sample-holder unit for two-dimensional nanopositioning.
  • To demonstrate the feasibility of near-field microscopy at the chip scale.
  • To characterize highly integrated optical structures using the developed system.

Main Methods:

  • Integration of a long-range traveling stage and a piezoelectric actuator for each displacement axis.
  • Incorporation of specific electronics designed with metrological considerations to improve repeatability.
