Nanonics Imaging: Breakthrough Study Sheds New Light on Graphene

Recent Study Demonstrates Innovative Enhanced Graphene Photodetector with Plasmonic Fractal Metasurface 

Graphene is a very promising material for photo detection due to its unique properties, e.g. ultrabroadband optical absorption, ultrafast electron speed, and wavelength independent absorption. However, single layer graphene - with only single atom depth - exhibits very low optical absorption, which limits its application in photodetection systems.

A recent study by Jieran Fang et al, published in NanoLetters, demonstrates a new path forward for significant photo detection enhancement in graphene.  In this paper, which was also highlighted in the February 2017 issue of the American Physical Society, researchers designed a gold fractal metasurface, similar in shape to a snowflake, and measured its electromagnetic character. As part of this study, a Nanonics MV2000 NSOM system was employed for plasmonic characterization of the snowflake metasurface with near field collection mode NSOM.

The obtained results demonstrated strong plasmonic generation near the branches and the edges of the fractal structure. It was demonstrated that the fractal metasurface integrated in graphene photodetector as source and drain provided enhancement factors of over 8-13. Additional advantages of this new enhanced graphene photodetector are broadband and polarization insensitive. This work indicates the great potential of enhanced graphene photodetectors in photodetection technology. 

piezosystems jena: NanoX technology enables high-speed piezo positioning

csm nanoX 200 72dpi 250x220mm d5daf890e4

Conventional piezo stages are usually designed in a way that the direction of motion of the piezo stacks is identical per axis. The forces generated by those stacks is then translated by solid state hinges. In dynamic operation however, this can cause the piezo stack to break if the generated pull forces exceed the internal preload. The motion of the actuator in the opposite direction of the stack motion is passive. A few years ago, piezosystem jena decided to tackle this challenge.

The result is the NanoX® design design, a completely new way of constructing a piezo stage. Here, piezo stacks are controlled opposed to each other. One stack is expanding while the other is contracting. Through this method an active backwards motion is achieved meaning even the backwards motion uses an actively expanding stack. This method of construction has several benefits for operational use. Not only is the stiffness increased, compared to stages with similar strokes, the stage can bear higher loads and generate higher forces.

Today, piezosystem jena offers many different models of the NanoX®. With the NanoSXY stages, there are even multi-axes systems available.

Edmund Optics Semiconductor Supermirrors

 semicon supermirror

Optical supermirrors have been rapidly gaining traction given their extremely high reflectivity and ultralow optical losses from scatter and absorption. They are crucial to many research and development efforts, as well as emerging industrial applications in spectroscopy, metrology, precise manufacturing, and sensing. For example, the ultra-low optical losses of optical supermirrors allow cavity ring-down spectroscopy systems to study gaseous samples with higher sensitivity and throughput than ever before.

To address this trend, a new class of Semiconductor Supermirrors has been developed that feature a single-crystal optical interference coating and provides excess optical losses (scatter and absorption) as low as 3ppm in the NIR (1064 – 1550nm) and 159ppm in the mid-IR (3 - 4μm). These Semiconductor Supermirrors outperform any other IR mirrors currently on the market due to their high reflectivity of >99.9%, low optical loss, low mechanical loss, and high thermal conductivity. Crystalline Mirror Solutions won a Prism award in the category of Materials and Coatings for this mid-IR coating technology.

Toptica: Frequency Comb basics

standard frequency comb

Frequency combs are very precise tools which are used for applications that require highest accuracy and resolution to measure the frequency of light. A frequency comb has an optical spectrum that consists of equidistant lines in the frequency domain. These lines serve as reference to measure unknown frequencies or to stabilize a laser to a certain frequency.

The discrete spectrum in the frequency domain corresponds to a regular train of ultrashort laser pulses in the time domain. This can be generated using a mode-locked laser oscillator whereas the repetition rate frep of the laser pulses corresponds to the distance between the discrete lines of the spectrum.
