An S3-type laser diode includes a p-type cladding layer (36) formed on an active layer (35) such that an inclined surface region thereof has a carrier concentration level of 1 x 1018 cm-3 or more, wherein the p-type cladding layer (36) has a thickness of 0.35m or more.ANAYAMA, ...
we propose an integrated paradigm for spin-decoupling PDCMs based on light emitting diode arrays that fully embed the photoresistor as a part of the meta-atom to independently manipulate the wavefront in different polarizations. As a proof of concept, PDCMs were simulated, fabricated, and measur...
As a first simple example of the novel capability to laser-print both, metals and semiconductors, we consider Pt–ZnO–Ag diodes in a lateral configuration. A diode composed of a platinum wire (~0.8 µm width), silver wires (~0.8 µm width), and a ZnO bar in between is sh...
significantly relieve the difficulties in material growth and device processing of different laser epi structures. We also expect that, with the advance of fabrication in increasing the integration level (heterogeneous integration), a fully integrated, foundry-based solution for this new type of laser ...
, 1979). Defects, unintentionally introduced during the fabrication process, propagate to the active region resulting in sudden failures. For reliability at high output powers, sophisticated NAM technology to provide complete facet passivation is required, since the AlGaAs QW active region has a high ...
(CW). At that time, the fabrication process was still immature and although there were no problems with output of CW light, there were still issues with intensity fluctuation, resonating, and unstable reflection (see figure below) due to effects of the pulse drive and reflected light, making ...
While PMMA is a low-cost material that is also easy to machine, a further simplification of the fabrication process might be achieved by 3D-printing the casings instead. As long as the precision is high enough to allow for the placement of the optical fibre with variations of no more than...
The purpose of in-situ monitoring is to collect process-relevant data simultaneous to fabrication, which can then be used to determine the state of the component throughout production. In general, this is useful for understanding the condition of the final product. Numerical modelling is also ofte...

We use fabrication of a 3D wireless LED as an example to explain the manufacturing workflow by FMAP (Fig. 1c) with details shown in Supplementary Fig. 1 and Supplementary Movie 1. The process starts with FFF of a few layers of a PC structure. Then, the laser is turned on to selectivel...
