III–V Integration on Si(100): Vertical Nanospades

On synergies and vertical integration

We analyze in an incomplete contracts model whether a supplier should be integrated if in addition to his investment level he chooses the degree of relationship specificity. A basic trade-off arises: While non-integration leads to higher investment incentives, potential synergies are foregone. Hence, integration can be optimal even though only the supplier makes an investment decision. This may...

Hybrid vertical-cavity laser integration on silicon

The hybrid vertical-cavity laser is a potential low current, high-efficiency, and small footprint light source for silicon photonics integration. As part of the development of such light sources we demonstrate hybrid-cavity VCSELs (HC-VCSELs) on silicon where a GaAs-based half-VCSEL is attached to a dielectric distributed Bragg reflector on silicon by adhesive bonding. HC-VCSELs at 850 nm with ...

A Note on Partial Vertical Integration

Empirical analysis [see, e.g., McDonald (1985)] suggests that partial vertical integration is a widespread phenomenon. However, there are hardly any theoretical explanations for this composition of industries. Both Arrow (1975) and Green (1986) explicitly allow for partial integration to occur. The former author takes the need for information to be the driving force behind vertical integration,...

Asymmetric Vertical Integration

We examine vertical backward integration in a reducedform model of successive oligopolies. Our key findings are: (i) There may be asymmetric equilibria where some firms integrate and others remain separated, even if firms are symmetric initially; (ii) Efficient firms are more likely to integrate vertically. As a result, integrated firms also tend to have a large market share. The driving force ...
