angular - Component as Injectable?

I am trying to build my own Modal component, that I would be able to reuse throughout my Angular2 Apps. I am considering different approaches, and I am wondering if it is possible to create @Component that also serves as @Injectable? I am considering this, as I want to build a template for the Modal, and keep it in one place.

Thanks

A component is injectable by default @Component() (or @Directive()) includes @Injectable().

Don't expect to get a specific instance of a component injected. This works for example with constructor(@Host() private parentComponent) where DI lookup is limited to parent injectors up to the injector of the host element.

Normally for your use case DynamicComponentLoader is used which only accepts the type of a component, not an instance. Dependency injection would just create an instance of the components class but not for example the associated view.
