Minister Penny Simmonds visits the photonics laboratory
The Minister of Science, Innovation and Technology toured the laboratory on 11 August, eight months after her predecessor made the same visit.
JPL meetings and an invited talk in Long Beach
Harald Schwefel met collaborators at NASA's Jet Propulsion Laboratory and gave an invited talk at Nonlinear Photonics, part of the Optica Advanced Photonics Congress.
Catalyst: Seeding award to build a partnership with NASA JPL
A two-year Catalyst: Seeding project pairs Tuwhiri's photonic sensor with a flight-proven JPL microwave spectrometer, aimed at measuring stratospheric water vapour.
Tuwhiri at the EGU General Assembly in Vienna
Florian Sedlmeir and Hannah Kessenich presented the programme's photonics and atmospheric science work to around 20,000 geoscientists.
Millimeter-Wave Atmospheric Radiometry via Nonlinear Optical Upconversion
The monitoring of the Earth’s atmospheric composition requires very sensitive satellite-based measurements that detect the thermal radiation emitted in the millimeter-wave and …
Minister Shane Reti visits the photonics laboratory
The Minister of Science, Innovation and Technology saw the up-conversion experiment that underpins the Tuwhiri instrument.
Visualization and selective manipulation of sub-terahertz whispering gallery modes

Dodd-Walls Centre annual symposium
Mallika Suresh represented the Tuwhiri photonics team at the Centre's annual gathering of New Zealand's photonics and quantum technology community.
Multichannel upconversion of terahertz radiation in an optical disk resonator
Second-order nonlinear optical processes allow the conversion of electromagnetic signals to a higher frequency domain. Such so-called "upconversion" processes have been of interest …
Tuwhiri Programme Kick-off Meeting
