Optics Letters
|November 2, 2018
Summary
Deterministic aperiodic photonic crystal nanobeams host nanocavities with multiple resonances. This enables excellent field overlap for advanced photonic devices.
Area of Science:
- Photonics and Nanotechnology
- Optical Physics
Background:
- Photonic crystals (PhCs) offer unique light manipulation properties.
- Deterministic aperiodic designs provide enhanced control over PhC properties.
- Nanocavities are crucial for confining light at the nanoscale.
Purpose of the Study:
- To investigate the resonant properties of nanocavities within deterministic aperiodic photonic crystal nanobeams.
- To explore the potential of these nanocavities for integrated photonic applications.
Main Methods:
- Numerical simulations of deterministic aperiodic photonic crystal nanobeam structures.
- Analysis of electromagnetic field distributions and mode profiles within nanocavities.
- Investigation of the relationship between bandgap properties and cavity resonances.
Main Results:
- A single nanocavity can support multiple mode-matched resonances.
- These resonances exhibit near-perfect field overlap within the cavity.
- Adjustable multiple bandgaps in the aperiodic PhC nanobeams enable this multi-resonance phenomenon.
Conclusions:
- Deterministic aperiodic PhC nanobeams offer a novel platform for multi-resonant nanocavities.
- This capability can advance the development of low-threshold lasers, nonlinear devices, optical filters, and on-chip sensors.

01:17Sign Test for Matched Pairs
411
The sign test for matched pairs offers a robust method for comparing two paired samples, often for the effects of an intervention in one of them. This method is very useful in situations where the underlying distribution of the data is unknown. The test compares two related samples—often pre- and post-treatment measurements on the same subjects—to determine if there are significant differences in their median values.
To conduct the sign test, we first calculate the differences in...

01:25The Anchoring-and-Adjustment Heuristic
7.8K
In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the...

01:12Adjusting a Traverse
384
In the site survey of a four-sided traverse, internal angles are essential to ensure geometric accuracy. The survey revealed that the sum of the measured internal angles was 359 degrees and 48 minutes, which is 12 minutes less than the expected 360 degrees. This discrepancy signals an error likely arising from measurement inaccuracies during the fieldwork.To rectify this error, the adjustment process involved distributing the 12-minute shortfall equally across the four internal angles. By...

01:07What is a Mode?
26.0K
The mode is one of the commonly used measures of a central tendency. It is defined as the most frequent value in a data set.
There can be more than one mode in a data set if multiple values have the same highest frequency. For instance, suppose that the Statistics exam scores of 20 students are: 50; 53; 59; 59; 63; 63; 72; 72; 72; 72; 72; 76; 78; 81; 83; 84; 84; 84; 90; 93. Here, the mode is 72, as it occurs most frequently, five times.
A data set with two modes is called bimodal. For example,...

02:42Ionic Crystal Structures
17.0K
Ionic crystals consist of two or more different kinds of ions that usually have different sizes. The packing of these ions into a crystal structure is more complex than the packing of metal atoms that are the same size.
Most monatomic ions behave as charged spheres, and their attraction for ions of opposite charge is the same in every direction. Consequently, stable structures for ionic compounds result (1) when ions of one charge are surrounded by as many ions as possible of the opposite...
